CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description Updated httpd packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) This update also fixes the following bugs : * The order of mod_proxy workers was not checked when httpd configuration was reloaded. When mod_proxy workers were removed, added, or their order was changed, their parameters and scores could become mixed. The order of mod_proxy workers has been made internally consistent during configuration reload. (BZ#1149906) * The local host certificate created during firstboot contained CA extensions, which caused the httpd service to return warning messages. This has been addressed by local host certificates being generated with the '-extensions v3_req' option. (BZ#906476) * The default mod_ssl configuration no longer enables support for SSL cipher suites using the single DES, IDEA, or SEED encryption algorithms. (BZ#1086771) * The apachectl script did not take into account the HTTPD_LANG variable set in the /etc/sysconfig/httpd file during graceful restarts. Consequently, httpd did not use a changed value of HTTPD_LANG when the daemon was restarted gracefully. The script has been fixed to handle the HTTPD_LANG variable correctly. (BZ#963146) * The mod_deflate module failed to check the original file size while extracting files larger than 4 GB, making it impossible to extract large files. Now, mod_deflate checks the original file size properly according to RFC1952, and it is able to decompress files larger than 4 GB. (BZ#1057695) * The httpd service did not check configuration before restart. When a configuration contained an error, an attempt to restart httpd gracefully failed. Now, httpd checks configuration before restart and if the configuration is in an inconsistent state, an error message is printed, httpd is not stopped and a restart is not performed. (BZ#1146194) * The SSL_CLIENT_VERIFY environment variable was incorrectly handled when the 'SSLVerifyClient optional_no_ca' and 'SSLSessionCache' options were used. When an SSL session was resumed, the SSL_CLIENT_VERIFY value was set to 'SUCCESS' instead of the previously set 'GENEROUS'. SSL_CLIENT_VERIFY is now correctly set to GENEROUS in this scenario. (BZ#1149703) * The ab utility did not correctly handle situations when an SSL connection was closed after some data had already been read. As a consequence, ab did not work correctly with SSL servers and printed 'SSL read failed' error messages. With this update, ab works as expected with HTTPS servers. (BZ#1045477) * When a client presented a revoked certificate, log entries were created only at the debug level. The log level of messages regarding a revoked certificate has been increased to INFO, and administrators are now properly informed of this situation. (BZ#1161328) In addition, this update adds the following enhancement : * A mod_proxy worker can now be set into drain mode (N) using the balancer-manager web interface or using the httpd configuration file. A worker in drain mode accepts only existing sticky sessions destined for itself and ignores all other requests. The worker waits until all clients currently connected to this worker complete their work before the worker is stopped. As a result, drain mode enables to perform maintenance on a worker without affecting clients. (BZ#767130) Users of httpd are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. After installing the updated packages, the httpd service will be restarted automatically.

    description The version of Oracle HTTP Server installed on the remote host is affected by multiple vulnerabilities in the Web Listener subcomponent : - An integer overflow condition exists in libxml2 within file xpath.c, related to XPath expressions when adding a new namespace note. An unauthenticated, remote attacker can exploit this, via a crafted XML file, to cause a denial of service condition or the execution of arbitary code. (CVE-2011-1944) - An integer overflow condition exists in the HTTP server, specifically in the ap_pregsub() function within file server/util.c, when the mod_setenvif module is enabled. A local attacker can exploit this to gain elevated privileges by using an .htaccess file with a crafted combination of SetEnvIf directives and HTTP request headers. (CVE-2011-3607) - A flaw exists in libxml2, known as the 'internal entity expansion' with linear complexity issue, that allows specially crafted XML files to consume excessive CPU and memory resources. An unauthenticated, remote attacker can exploit this to cause a denial of service condition by using a specially crafted XML file containing an entity declaration with long replacement text and many references to this entity. (CVE-2013-0338) - An out-of-bounds read error exists in libxml2 within file parser.c due to a failure to check for the XML_PARSER_EOF state. An unauthenticated, remote attacker can exploit this, via a specially crafted document that ends abruptly, to cause a denial of service condition. (CVE-2013-2877) - A flaw exists within the mod_headers module in the HTTP server which allows bypassing the 'RequestHeader unset' directives. An unauthenticated, remote attacker can exploit this to inject arbitrary headers. This is done by placing a header in the trailer portion of data being sent using chunked transfer encoding. (CVE-2013-5704) - A flaw exists in the dav_xml_get_cdata() function in file main/util.c within the HTTP server mod_dav module due to incorrect stripping of whitespace characters from the CDATA sections. An unauthenticated, remote attacker via a specially crafted DAV WRITE request, can exploit this to cause a denial of service condition. (CVE-2013-6438) - A flaw exists in the log_cookie() function in file mod_log_config.c within the HTTP server mod_log_config module due to improper handling of specially crafted cookies during truncation. An unauthenticated, remote attacker can exploit this to cause a denial of service condition via a segmentation fault. (CVE-2014-0098) - A flaw exists in libxml2, specifically in the xmlParserHandlePEReference() function in file parser.c, due to loading external parameter entities even when entity substitution is disabled. An unauthenticated, remote attacker can exploit this issue, via a specially crafted XML file, to conduct XML External Entity (XXE) attacks that exhaust CPU and memory resources, resulting in a denial of service condition. (CVE-2014-0191) - A race condition exists in the HTTP server within the mod_status module when using a threaded Multi-Processing Module (MPM). If an unauthenticated, remote attacker is able to access status pages served by mod_status, the attacker can exploit this issue, by sending specially crafted requests, to cause the httpd child process to crash or possibly execute arbitrary code with the privileges of the user running the web server. (CVE-2014-0226) - An unspecified flaw exists in the Web Listener subcomponent that allows an unauthenticated, remote attacker to impact confidentiality, integrity, and availability.

    description mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory. (CVE-2014-8109) A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) A NULL pointer dereference flaw was found in the way the mod_cache httpd module handled Content-Type headers.

    description Updated httpd packages that fix two security issues, several bugs, and add various enhancements are for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) A NULL pointer dereference flaw was found in the way the mod_cache httpd module handled Content-Type headers. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP server was configured to proxy to a server with caching enabled. (CVE-2014-3581) This update also fixes the following bugs : * Previously, the mod_proxy_fcgi Apache module always kept the back-end connections open even when they should have been closed. As a consequence, the number of open file descriptors was increasing over the time. With this update, mod_proxy_fcgi has been fixed to check the state of the back-end connections, and it closes the idle back-end connections as expected. (BZ#1168050) * An integer overflow occurred in the ab utility when a large request count was used. Consequently, ab terminated unexpectedly with a segmentation fault while printing statistics after the benchmark. This bug has been fixed, and ab no longer crashes in this scenario. (BZ#1092420) * Previously, when httpd was running in the foreground and the user pressed Ctrl+C to interrupt the httpd processes, a race condition in signal handling occurred. The SIGINT signal was sent to all children followed by SIGTERM from the main process, which interrupted the SIGINT handler. Consequently, the affected processes became unresponsive or terminated unexpectedly. With this update, the SIGINT signals in the child processes are ignored, and httpd no longer hangs or crashes in this scenario. (BZ#1131006) In addition, this update adds the following enhancements : * With this update, the mod_proxy module of the Apache HTTP Server supports the Unix Domain Sockets (UDS). This allows mod_proxy back ends to listen on UDS sockets instead of TCP sockets, and as a result, mod_proxy can be used to connect UDS back ends. (BZ#1168081) * This update adds support for using the SetHandler directive together with the mod_proxy module. As a result, it is possible to configure SetHandler to use proxy for incoming requests, for example, in the following format: SetHandler 'proxy:fcgi://127.0.0.1:9000'. (BZ#1136290) * The htaccess API changes introduced in httpd 2.4.7 have been backported to httpd shipped with Red Hat Enterprise Linux 7.1. These changes allow for the MPM-ITK module to be compiled as an httpd module. (BZ#1059143) All httpd users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. After installing the updated packages, the httpd daemon will be restarted automatically.

An authenticated, remote attacker can exploit this to gain access to sensitive information. (CVE-2014-8161) - A flaw exists within the Domain Name Service due to an error in the code used to follow delegations. A remote attacker, with a maliciously-constructed zone or query, can cause the service to issue unlimited queries, resulting in resource exhaustion. (CVE-2014-8500) - A flaw exists in the lua_websocket_read() function in the 'mod_lua' module due to incorrect handling of WebSocket PING frames. A remote attacker can exploit this, by sending a crafted WebSocket PING frame after a Lua script has called the wsupgrade() function, to crash a child process, resulting in a denial of service condition. (CVE-2015-0228) - Multiple vulnerabilities exist due to several buffer overflow errors related to the 'to_char' functions. An authenticated, remote attacker can exploit these issues to cause a denial of service or arbitrary code execution. (CVE-2015-0241) - Multiple vulnerabilities exist due to several stack-based buffer overflow errors in various *printf() functions. The overflows are due to improper validation of user-supplied input when formatting a floating point number where the requested precision is greater than approximately 500. An authenticated, remote attacker can exploit these issues to cause a denial of service or arbitrary code execution. (CVE-2015-0242) - Multiple vulnerabilities exist due to an overflow condition in multiple functions in the 'pgcrypto' extension. The overflows are due to improper validation of user-supplied input when tracking memory sizes. An authenticated, remote attacker can exploit these issues to cause a denial of service or arbitrary code execution. (CVE-2015-0243) - A SQL injection vulnerability exists due to improper sanitization of user-supplied input when handling crafted binary data within a command parameter. An authenticated, remote attacker can exploit this issue to inject or manipulate SQL queries, allowing the manipulation or disclosure of arbitrary data. (CVE-2015-0244) - A NULL pointer dereference flaw exists in the read_request_line() function due to a failure to initialize the protocol structure member. A remote attacker can exploit this flaw, on installations that enable the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI, by sending a request that lacks a method, to cause a denial of service condition. (CVE-2015-0253) - A denial of service vulnerability exists due to an error relating to DNSSEC validation and the managed-keys feature. A remote attacker can trigger an incorrect trust-anchor management scenario in which no key is ready for use, resulting in an assertion failure and daemon crash. (CVE-2015-1349) - A flaw exists in PostgreSQL client disconnect timeout expiration that is triggered when a timeout interrupt is fired partway through the session shutdown sequence. (CVE-2015-3165) - A flaw exists in the printf() functions due to a failure to check for errors. A remote attacker can use this to gain access to sensitive information. (CVE-2015-3166) - The pgcrypto component in PostgreSQL has multiple error messages for decryption with an incorrect key. A remote attacker can use this to recover keys from other systems. (CVE-2015-3167) - A flaw exists in the chunked transfer coding implementation due to a failure to properly parse chunk headers. A remote attacker can exploit this to conduct HTTP request smuggling attacks. (CVE-2015-3183) - A flaw exists in the ap_some_auth_required() function due to a failure to consider that a Require directive may be associated with an authorization setting rather than an authentication setting. A remote attacker can exploit this, if a module that relies on the 2.2 API behavior exists, to bypass intended access restrictions. (CVE-2015-3185) - Multiple unspecified XML flaws exist in the Wiki Server based on Twisted. (CVE-2015-5911)

    description From Red Hat Security Advisory 2015:0325 : Updated httpd packages that fix two security issues, several bugs, and add various enhancements are for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. A flaw was found in the way httpd handled HTTP Trailer headers when processing requests using chunked encoding. A malicious client could use Trailer headers to set additional HTTP headers after header processing was performed by other modules. This could, for example, lead to a bypass of header restrictions defined with mod_headers. (CVE-2013-5704) A NULL pointer dereference flaw was found in the way the mod_cache httpd module handled Content-Type headers. A malicious HTTP server could cause the httpd child process to crash when the Apache HTTP server was configured to proxy to a server with caching enabled. (CVE-2014-3581) This update also fixes the following bugs : * Previously, the mod_proxy_fcgi Apache module always kept the back-end connections open even when they should have been closed. As a consequence, the number of open file descriptors was increasing over the time. With this update, mod_proxy_fcgi has been fixed to check the state of the back-end connections, and it closes the idle back-end connections as expected. (BZ#1168050) * An integer overflow occurred in the ab utility when a large request count was used. Consequently, ab terminated unexpectedly with a segmentation fault while printing statistics after the benchmark. This bug has been fixed, and ab no longer crashes in this scenario. (BZ#1092420) * Previously, when httpd was running in the foreground and the user pressed Ctrl+C to interrupt the httpd processes, a race condition in signal handling occurred. The SIGINT signal was sent to all children followed by SIGTERM from the main process, which interrupted the SIGINT handler. Consequently, the affected processes became unresponsive or terminated unexpectedly. With this update, the SIGINT signals in the child processes are ignored, and httpd no longer hangs or crashes in this scenario. (BZ#1131006) In addition, this update adds the following enhancements : * With this update, the mod_proxy module of the Apache HTTP Server supports the Unix Domain Sockets (UDS). This allows mod_proxy back ends to listen on UDS sockets instead of TCP sockets, and as a result, mod_proxy can be used to connect UDS back ends. (BZ#1168081) * This update adds support for using the SetHandler directive together with the mod_proxy module. As a result, it is possible to configure SetHandler to use proxy for incoming requests, for example, in the following format: SetHandler 'proxy:fcgi://127.0.0.1:9000'. (BZ#1136290) * The htaccess API changes introduced in httpd 2.4.7 have been backported to httpd shipped with Red Hat Enterprise Linux 7.1. These changes allow for the MPM-ITK module to be compiled as an httpd module. (BZ#1059143) All httpd users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. After installing the updated packages, the httpd daemon will be restarted automatically.

See directives DeflateInflateLimitRequestBody, DeflateInflateRatioLimit, and DeflateInflateRatioBurst. mod_cgid: Fix a denial of service against CGI scripts that do not consume stdin that could lead to lingering HTTPD child processes filling up the scoreboard and eventually hanging the server. By default, the client I/O timeout (Timeout directive) now applies to communication with scripts. The CGIDScriptTimeout directive can be used to set a different timeout for communication with scripts. Fix a race condition in scoreboard handling, which could lead to a heap buffer overflow. core: HTTP trailers could be used to replace HTTP headers late during request processing, potentially undoing or otherwise confusing modules that examined or modified request headers earlier.

    description According to its banner, the version of Apache 2.2.x running on the remote host is prior to 2.2.28. It is, therefore, affected by the following vulnerabilities : - A flaw exists within the 'mod_headers' module which allows a remote attacker to inject arbitrary headers. This is done by placing a header in the trailer portion of data being sent using chunked transfer encoding. (CVE-2013-5704) - A flaw exists within the 'mod_deflate' module when handling highly compressed bodies. Using a specially crafted request, a remote attacker can exploit this to cause a denial of service by exhausting memory and CPU resources. (CVE-2014-0118) - The 'mod_status' module contains a race condition that can be triggered when handling the scoreboard. A remote attacker can exploit this to cause a denial of service, execute arbitrary code, or obtain sensitive credential information. (CVE-2014-0226) - The 'mod_cgid' module lacks a time out mechanism. Using a specially crafted request, a remote attacker can use this flaw to cause a denial of service by causing child processes to linger indefinitely, eventually filling up the scoreboard. (CVE-2014-0231) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
