ID CVE-2018-1301
Summary A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.

Impact:
Exploitability:
CWE CWE-119
CAPEC
  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.
  • Overflow Binary Resource File
    An attack of this type exploits a buffer overflow vulnerability in the handling of binary resources. Binary resources may include music files like MP3, image files like JPEG files, and any other binary file. These attacks may pass unnoticed to the client machine through normal usage of files, such as a browser loading a seemingly innocent JPEG file. This can allow the attacker access to the execution stack and execute arbitrary code in the target process. This attack pattern is a variant of standard buffer overflow attacks using an unexpected vector (binary files) to wrap its attack and open up a new attack vector. The attacker is required to either directly serve the binary content to the victim, or place it in a locale like a MP3 sharing application, for the victim to download. The attacker then is notified upon the download or otherwise locates the vulnerability opened up by the buffer overflow.
  • Buffer Overflow via Symbolic Links
    This type of attack leverages the use of symbolic links to cause buffer overflows. An attacker can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.
  • Overflow Variables and Tags
    This type of attack leverages the use of tags or variables from a formatted configuration data to cause buffer overflow. The attacker crafts a malicious HTML page or configuration file that includes oversized strings, thus causing an overflow.
  • Buffer Overflow via Parameter Expansion
    In this attack, the target software is given input that the attacker knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
  • Buffer Overflow in an API Call
    This attack targets libraries or shared code modules which are vulnerable to buffer overflow attacks. An attacker who has access to an API may try to embed malicious code in the API function call and exploit a buffer overflow vulnerability in the function's implementation. All clients that make use of the code library thus become vulnerable by association. This has a very broad effect on security across a system, usually affecting more than one software process.
  • Buffer Overflow in Local Command-Line Utilities
    This attack targets command-line utilities available in a number of shells. An attacker can leverage a vulnerability found in a command-line utility to escalate privilege to root.

    description This update for apache2 fixes the following issues : - CVE-2018-1283: when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a \'Session\' header leading to unexpected behavior [bsc#1086814]. - CVE-2018-1301: due to an out of bound access after a size limit being reached by reading the HTTP header, a specially crafted request could lead to remote denial of service. [bsc#1086817] - CVE-2018-1303: a specially crafted HTTP request header could lead to crash due to an out of bound read while preparing data to be cached in shared memory.[bsc#1086813] - CVE-2017-15715: a regular expression could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. leading to corruption of uploaded files.[bsc#1086774] - CVE-2018-1312: when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. [bsc#1086775] - CVE-2017-15710: mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. [bsc#1086820] - CVE-2018-1302: when an HTTP/2 stream was destroyed after being handled, it could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. [bsc#1086820] This update was imported from the SUSE:SLE-12-SP2:Update update project.

    description Use-after-free on HTTP/2 stream shutdown When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. (CVE-2018-1302) Bypass with a trailing newline in the file name In Apache httpd 2.4.0 to 2.4.29, the expression specified in could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename. (CVE-2017-15715) Out of bounds read in mod_cache_socache can allow a remote attacker to cause a denial of service A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability. (CVE-2018-1303) Improper handling of headers in mod_session can allow a remote user to modify session data for CGI applications It has been discovered that the mod_session module of Apache HTTP Server (httpd), through version 2.4.29, has an improper input validation flaw in the way it handles HTTP session headers in some configurations. A remote attacker may influence their content by using a 'Session' header. (CVE-2018-1283) Out of bound write in mod_authnz_ldap when using too small Accept-Language values In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string.

This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage. (CVE-2018-1301) Weak Digest auth nonce generation in mod_auth_digest In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed.

[bsc#1086817] - CVE-2018-1303: a specially crafted HTTP request header could lead to crash due to an out of bound read while preparing data to be cached in shared memory.[bsc#1086813] - CVE-2017-15715: a regular expression could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. leading to corruption of uploaded files.[bsc#1086774] - CVE-2018-1312: when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. [bsc#1086775] - CVE-2017-15710: mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all. [bsc#1086820] - CVE-2018-1302: when an HTTP/2 stream was destroyed after being handled, it could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk. [bsc#1086820] Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.33. It is, therefore, affected by multiple vulnerabilities: - An out of bounds write vulnerability exists in mod_authnz_ldap with AuthLDAPCharsetConfig enabled. An unauthenticated, remote attacker can exploit this, via the Accept-Language header value, to cause the application to stop responding. (CVE-2017-15710) - An arbitrary file upload vulnerability exists in the FilesMatch component where a malicious filename can be crafted to match the expression check for a newline character. An unauthenticated, remote attacker can exploit this, via newline character, to upload arbitrary files on the remote host subject to the privileges of the user. (CVE-2017-15715) - A session management vulnerability exists in the mod_session component due to SessionEnv being enabled and forwarding it's session data to the CGI Application. An unauthenticated, remote attacker can exploit this, via tampering the HTTP_SESSION and using a session header, to influence content. (CVE-2018-1283) - An out of bounds access vulnerability exists when the size limit is reached. An unauthenticated, remote attacker can exploit this, to cause the Apache HTTP Server to crash. (CVE-2018-1301) - A write after free vulnerability exists in HTTP/2 stream due to a NULL pointer being written to an area of freed memory. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2018-1302) - An out of bounds read vulnerability exists in mod_cache_socache. An unauthenticated, remote attacker can exploit this, via a specially crafted HTTP request header to cause the application to stop responding. (CVE-2018-1303) - A weak digest vulnerability exists in the HTTP digest authentication challenge. An unauthenticated, remote attacker can exploit this in a cluster of servers configured to use a common digest authentication, to replay HTTP requests across servers without being detected. (CVE-2018-1312) Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

    description Several vulnerabilities have been found in the Apache HTTPD server. CVE-2017-15710 Alex Nichols and Jakob Hirsch reported that mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, could cause an of bound write if supplied with a crafted Accept-Language header. This could potentially be used for a Denial of Service attack. CVE-2018-1301 Robert Swiecki reported that a specially crafted request could have crashed the Apache HTTP Server, due to an out of bound access after a size limit is reached by reading the HTTP header. CVE-2018-1312 Nicolas Daniels discovered that when generating an HTTP Digest authentication challenge, the nonce sent by mod_auth_digest to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. For Debian 7 'Wheezy', these problems have been fixed in version 2.2.22-13+deb7u13. We recommend that you upgrade your apache2 packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
