TITLE

Apache HTTP Server of mod_proxy Vulnerability in module sending requests to intranet server

DESCRIPTION

The mod_proxy module in the Apache HTTP Server 1.3.x through 1.3.42, 2.0.x through 2.0.64, and 2.2.x through 2.2.21 does not properly interact with use of (1) RewriteRule and (2) ProxyPassMatch pattern matches for configuration of a reverse proxy, which allows remote attackers to send requests to intranet servers via a malformed URI containing an initial @ (at sign) character. Apache HTTP Server is prone to an information disclosure vulnerability. An attacker can exploit this vulnerability to gain access to sensitive information. 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. This is a violation of the privilege separation between the apache2 processes and could potentially be used to worsen the impact of other vulnerabilities. This could allow a remote attacker using cross site scripting to steal authentication cookies. For the oldstable distribution (lenny), these problems have been fixed in version apache2 2.2.9-10+lenny12. For the stable distribution (squeeze), these problems have been fixed in version apache2 2.2.16-6+squeeze6 For the testing distribution (wheezy), these problems will be fixed in version 2.2.22-1. For the unstable distribution (sid), these problems have been fixed in version 2.2.22-1. We recommend that you upgrade your apache2 packages. The new version number for the oldstable distribution is 2.2.6-02-1+lenny7. In the stable distribution, apache2-mpm-itk has the same version number as apache2. (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. Solution: The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, back up your existing JBoss Enterprise Web Server installation (including all applications and configuration files). This version of Apache is principally a security and bug fix release, including the following significant security fixes: * SECURITY: CVE-2011-3368 (cve.mitre.org) Reject requests where the request-URI does not match the HTTP specification, preventing unexpected expansion of target URLs in some reverse proxy configurations. * SECURITY: CVE-2011-3607 (cve.mitre.org) 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. * SECURITY: CVE-2011-4317 (cve.mitre.org) Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations. * SECURITY: CVE-2012-0021 (cve.mitre.org) 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. * SECURITY: CVE-2012-0053 (cve.mitre.org) Fixed an issue in error responses that could expose "httpOnly" cookies when no custom ErrorDocument is specified for status code 400. The Apache HTTP Project thanks halfdog, Context Information Security Ltd, Prutha Parikh of Qualys, and Norman Hippert for bringing these issues to the attention of the security team. We consider this release to be the best version of Apache available, and encourage users of all prior versions to upgrade. Apache HTTP Server 2.2.22 is available for download from: http://httpd.apache.org/download.cgi Please see the CHANGES_2.2 file, linked from the download page, for a full list of changes. A condensed list, CHANGES_2.2.22 includes only those changes introduced since the prior 2.2 release. A summary of all of the security vulnerabilities addressed in this and earlier releases is available: http://httpd.apache.org/security/vulnerabilities_22.html This release includes the Apache Portable Runtime (APR) version 1.4.5 and APR Utility Library (APR-util) version 1.4.2, bundled with the tar and zip distributions. The APR libraries libapr and libaprutil (and on Win32, libapriconv version 1.2.1) must all be updated to ensure binary compatibility and address many known security and platform bugs. APR-util version 1.4 represents a minor version upgrade from earlier httpd source distributions, which previously included version 1.3. Apache 2.2 offers numerous enhancements, improvements, and performance boosts over the 2.0 codebase. For an overview of new features introduced since 2.0 please see: http://httpd.apache.org/docs/2.2/new_features_2_2.html This release builds on and extends the Apache 2.0 API. Modules written for Apache 2.0 will need to be recompiled in order to run with Apache 2.2, and require minimal or no source code changes. http://svn.apache.org/repos/asf/httpd/httpd/branches/2.2.x/VERSIONING When upgrading or installing this version of Apache, please bear in mind that if you intend to use Apache with one of the threaded MPMs (other than the Prefork MPM), you must ensure that any modules you will be using (and the libraries they depend on) are thread-safe.

Summary: Updated httpd packages that fix two security issues and one bug 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. 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) 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-2011:1245 update introduced regressions in the way httpd handled certain Range HTTP header values. This update corrects those regressions. (BZ#736592) 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 must be restarted for the update to take effect. 4.

When using the RewriteRule or ProxyPassMatch directives to configure a reverse proxy using a pattern match, it is possible to inadvertently expose internal servers to remote users who send carefully crafted requests. The server did not validate that the input to the pattern match was a valid path string, so a pattern could expand to an unintended target URL. The documentation has been updated to reflect the more general risks with pattern matching in a reverse proxy configuration. Details: ======== A configuration like one of the following examples: RewriteRule (.*)\.(jpg|gif|png) http://images.example.com$1.$2 [P] ProxyPassMatch (.*)\.(jpg|gif|png) http://images.example.com$1.$2 could result in an exposure of internal servers. A request of the form: GET @other.example.com/something.png HTTP/1.1 would get translated to a target of: http://images.example.com@other.example.com/something.png This will cause the proxy to connect to the hostname "other.example.com", as the "images.example.com@" segment would be treated as user credentials when parsing the URL. This would allow a remote attacker the ability to proxy to hosts other than those expected, which could be a security exposure in some circumstances. The request-URI string in this example, "@other.example.com/something.png", is not valid according to the HTTP specification, since it neither an absolute URI ("http://example.com/path") nor an absolute path ("/path"). For future releases, the server has been patched to reject such requests, instead returning a "400 Bad Request" error. Actions: ======== Apache HTTPD users should examine their configuration files to determine if they have used an insecure configuration for reverse proxying. Affected users can update their configuration, or apply the patch from: http://www.apache.org/dist/httpd/patches/apply_to_2.2.21/ For example, the above RewriteRule could be changed to: RewriteRule /(.*)\.(jpg|gif|png) http://images.example.com/$1.$2 [P] to ensure the pattern only matches against paths with a leading "/".
