    NASL id DEBIAN_DSA-2405.NASL
    description Several vulnerabilities have been found in the Apache HTTPD Server : - CVE-2011-3607 : An integer overflow in ap_pregsub() could allow local attackers to execute arbitrary code at elevated privileges via crafted .htaccess files. - CVE-2011-3368 CVE-2011-3639 CVE-2011-4317 : The Apache HTTP Server did not properly validate the request URI for proxied requests. In certain reverse proxy configurations using the ProxyPassMatch directive or using the RewriteRule directive with the [P] flag, a remote attacker could make the proxy connect to an arbitrary server. This could allow the attacker to access internal servers that are not otherwise accessible from the outside. The three CVE ids denote slightly different variants of the same issue. Note that, even with this issue fixed, it is the responsibility of the administrator to ensure that the regular expression replacement pattern for the target URI does not allow a client to append arbitrary strings to the host or port parts of the target URI. For example, the configuration ProxyPassMatch ^/mail(.*) http://internal-host$1 is still insecure and should be replaced by one of the following configurations : ProxyPassMatch ^/mail(/.*) http://internal-host$1 ProxyPassMatch ^/mail/(.*) http://internal-host/$1 - CVE-2012-0031 : An apache2 child process could cause the parent process to crash during shutdown. This is a violation of the privilege separation between the apache2 processes and could potentially be used to worsen the impact of other vulnerabilities. - CVE-2012-0053 : The response message for error code 400 (bad request) could be used to expose 'httpOnly' cookies. This could allow a remote attacker using cross site scripting to steal authentication cookies.

    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. (CVE-2014-6571) - An unspecified flaw exists in the J2EE subcomponent that allows an unauthenticated, remote attacker to disclose potentially sensitive information. (CVE-2015-0372) - An unspecified flaw exists in the Web Listener subcomponent that allows an unauthenticated, remote attacker to cause a denial of service condition. (CVE-2015-0386)

(CVE-2011-3368) - Fix integer overflow in ap_pregsub() which, when the mod_setenvif module is enabled, could allow local users to gain privileges via a .htaccess file. (CVE-2011-3607) - Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations. (CVE-2011-4317) - mod_log_config: Fix segfault (crash) when the '%{cookiename}C' log format string is in use and a client sends a nameless, valueless cookie, causing a denial of service. The issue existed since version 2.2.17. (CVE-2012-0021) - Fix scoreboard issue which could allow an unprivileged child process could cause the parent to crash at shutdown rather than terminate cleanly. (CVE-2012-0031) - Fixed an issue in error responses that could expose 'httpOnly' cookies when no custom ErrorDocument is specified for status code 400.

  • NASL family CentOS Local Security Checks
    NASL id CENTOS_RHSA-2012-0128.NASL
    description Updated httpd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate 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 Apache HTTP Server is a popular web server. It was discovered that the fix for CVE-2011-3368 (released via RHSA-2011:1391) did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially crafted URI. (CVE-2011-3639, CVE-2011-4317) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a '.htaccess' file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the 'apache' user. (CVE-2011-3607) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon will be restarted automatically.

    description - httpd-2.2.x-bnc743743-CVE-2012-0053-server_protocol_c-cookie_exposure.diff addresses CVE-2012-0053: error responses can expose cookies when no custom 400 error code ErrorDocument is configured. [bnc#743743] - httpd-2.2.x-bnc741243-CVE-2012-0031-scoreboard_handling.diff: scoreboard corruption (shared mem segment) by child causes crash of privileged parent (invalid free()) during shutdown. This is rated low impact. Notice: https://svn.apache.org/viewvc?view=revision&revision=1230065 makes a change to the struct global_score, which causes binary incompatibility. The change in above patch only goes as far as the binary compatibility allows; the vulnerability is completely fixed, though. CVE-2012-0031 [bnc#741243] - /etc/init.d/apache2: new argument 'check-reload'. Exits 1 if httpd2 runs on deleted binaries such as after package update, else 0. This is used by equally modified /etc/logrotate.d/apache2, which uses '/etc/init.d/apache2 check-reload' in its prerotate script. These changes prevent httpd2 from being (gracefully) reloaded by logrotate, executed by cron, if new binaries have been installed. Instead, a warning is printed on stdout and is being logged to the syslogs. If this happens, apache's logs are NOT rotated, and the running processes are left untouched. This limits the maximum damage of log rotation to unrotated logs. '/etc/init.d/apache2 restart' (or 'rcapache2 restart') must be executed manually in such a case. [bnc#728876] - httpd-2.2.x-bnc729181-CVE-2011-3607-int_overflow.diff: Fix for integer overflow in server/util.c also known as CVE-2011-3607. [bnc#729181] - enable build and configuration of mod_reqtimeout.c module by default in /etc/sysconfig/apache2 (APACHE_MODULES=...). This does not change already existing sysconfig files, the module is only activated via sysconfig if this package is installed without pre-existing sysconfig file. See new file /etc/apache2/mod_reqtimeout.conf for configurables. Helps against Slowloris.pl DoS vulnerability that consists of eating up request slots by very slowly submitting the request. Note that mod_reqtimeout limits requests based on a lower boundary of request speed, not an upper boundary! CVE-2007-6750 [bnc#738855].

    description It was discovered that the Apache HTTP Server incorrectly handled the SetEnvIf .htaccess file directive. An attacker having write access to a .htaccess file may exploit this to possibly execute arbitrary code. (CVE-2011-3607) Prutha Parikh discovered that the mod_proxy module did not properly interact with the RewriteRule and ProxyPassMatch pattern matches in the configuration of a reverse proxy. This could allow remote attackers to contact internal webservers behind the proxy that were not intended for external exposure. (CVE-2011-4317) Rainer Canavan discovered that the mod_log_config module incorrectly handled a certain format string when used with a threaded MPM. A remote attacker could exploit this to cause a denial of service via a specially- crafted cookie. This issue only affected Ubuntu 11.04 and 11.10. (CVE-2012-0021) It was discovered that the Apache HTTP Server incorrectly handled certain type fields within a scoreboard shared memory segment. A local attacker could exploit this to to cause a denial of service. (CVE-2012-0031) Norman Hippert discovered that the Apache HTTP Server incorrecly handled header information when returning a Bad Request (400) error page. A remote attacker could exploit this to obtain the values of certain HTTPOnly cookies. (CVE-2012-0053). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory.

    description CVE MITRE reports : An exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker. Integer overflow in the ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, allows local users to gain privileges via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, leading to a heap-based buffer overflow. An additional exposure was found when using mod_proxy in reverse proxy mode. In certain configurations using RewriteRule with proxy flag or ProxyPassMatch, a remote attacker could cause the reverse proxy to connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to attacker. A flaw was found in mod_log_config. If the '%{cookiename}C' log format string is in use, a remote attacker could send a specific cookie causing a crash. This crash would only be a denial of service if using a threaded MPM. A flaw was found in the handling of the scoreboard. An unprivileged child process could cause the parent process to crash at shutdown rather than terminate cleanly. A flaw was found in the default error response for status code 400. This flaw could be used by an attacker to expose 'httpOnly' cookies when no custom ErrorDocument is specified.

    description Updated httpd packages that fix multiple security issues and one bug are now available for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 5 and 6. The Red Hat Security Response Team has rated this update as having moderate 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 Apache HTTP Server ('httpd') is the namesake project of The Apache Software Foundation. It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker. (CVE-2011-3368) It was discovered that mod_proxy_ajp incorrectly returned an 'Internal Server Error' response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period or until all back-end servers were marked as failed. (CVE-2011-3348) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a '.htaccess' file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the 'apache' user. (CVE-2011-3607) A NULL pointer dereference flaw was found in the httpd mod_log_config module. In configurations where cookie logging is enabled, a remote attacker could use this flaw to crash the httpd child process via an HTTP request with a malformed Cookie header. (CVE-2012-0021) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) Red Hat would like to thank Context Information Security for reporting the CVE-2011-3368 issue. This update also fixes the following bug : * The fix for CVE-2011-3192 provided by the RHSA-2011:1329 update introduced a regression in the way httpd handled certain Range HTTP header values. This update corrects this regression. (BZ#749071) All users of JBoss Enterprise Web Server 1.0.2 should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, users must restart the httpd service for the update to take effect.

    description The Apache HTTP Server is a popular web server. It was discovered that the fix for CVE-2011-3368 (released via a previous update) did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request. (CVE-2011-3639) The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies. (CVE-2012-0053) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions. An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a '.htaccess' file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the 'apache' user. (CVE-2011-3607) A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown. (CVE-2012-0031) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon will be restarted automatically.

  • NASL family Web Servers
    NASL id APACHE_2_0_65.NASL
    description According to its banner, the version of Apache 2.0.x running on the remote host is prior to 2.0.65. It is, therefore, affected by several vulnerabilities : - A flaw exists in the byte-range filter, making it vulnerable to denial of service. (CVE-2011-3192) - A flaw exists in 'mod_proxy' where it doesn't properly interact with 'RewriteRule' and 'ProxyPassMatch' in reverse proxy configurations. (CVE-2011-3368) - A privilege escalation vulnerability exists relating to a heap-based buffer overflow in 'ap_pregsub' function in 'mod_setenvif' module via .htaccess file. (CVE-2011-3607) - A local security bypass vulnerability exists within scoreboard shared memory that may allow the child process to cause the parent process to crash. (CVE-2012-0031) - A flaw exists within the status 400 code when no custom ErrorDocument is specified that could disclose 'httpOnly' cookies. (CVE-2012-0053) - A flaw exists in the 'RewriteLog' function where it fails to sanitize escape sequences written to log files, which could result in arbitrary command execution. (CVE-2013-1862) Note that the remote web server may not actually be affected by these vulnerabilities. Nessus did not try to determine whether the affected modules are in use nor did it test for the issues themselves.

  • NASL family Web Servers
    NASL id APACHE_2_2_22.NASL
    description According to its banner, the version of Apache 2.2.x installed on the remote host is prior to 2.2.22. It is, therefore, potentially affected by the following vulnerabilities : - When configured as a reverse proxy, improper use of the RewriteRule and ProxyPassMatch directives could cause the web server to proxy requests to arbitrary hosts. This could allow a remote attacker to indirectly send requests to intranet servers. (CVE-2011-3368, CVE-2011-4317) - A heap-based buffer overflow exists when mod_setenvif module is enabled and both a maliciously crafted 'SetEnvIf' directive and a maliciously crafted HTTP request header are used. (CVE-2011-3607) - A format string handling error can allow the server to be crashed via maliciously crafted cookies. (CVE-2012-0021) - An error exists in 'scoreboard.c' that can allow local attackers to crash the server during shutdown. (CVE-2012-0031) - An error exists in 'protocol.c' that can allow 'HTTPOnly' cookies to be exposed to attackers through the malicious use of either long or malformed HTTP headers. (CVE-2012-0053) - An error in the mod_proxy_ajp module when used to connect to a backend server that takes an overly long time to respond could lead to a temporary denial of service. (CVE-2012-4557) Note that Nessus did not actually test for these flaws, but instead has relied on the version in the server's banner.
