Red Hat Security Advisory 2013-0815-01

Red Hat Security Advisory 2013-0815-01 - The Apache HTTP Server is a popular web server. Cross-site scripting flaws were found in the mod_proxy_balancer module's manager web interface. If a remote attacker could trick a user, who was logged into the manager web interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's manager interface session. It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user.

3. Description:

The Apache HTTP Server is a popular web server.

Cross-site scripting (XSS) flaws were found in the mod_proxy_balancer
module's manager web interface. If a remote attacker could trick a user,
who was logged into the manager web interface, into visiting a
specially-crafted URL, it would lead to arbitrary web script execution in
the context of the user's manager interface session. (CVE-2012-4558)

It was found that mod_rewrite did not filter terminal escape sequences from
its log file. If mod_rewrite was configured with the RewriteLog directive,
a remote attacker could use specially-crafted HTTP requests to inject
terminal escape sequences into the mod_rewrite log file. If a victim viewed
the log file with a terminal emulator, it could result in arbitrary command
execution with the privileges of that user. (CVE-2013-1862)

Cross-site scripting (XSS) flaws were found in the mod_info, mod_status,
mod_imagemap, mod_ldap, and mod_proxy_ftp modules. An attacker could
possibly use these flaws to perform XSS attacks if they were able to make
the victim's browser generate an HTTP request with a specially-crafted Host
header. (CVE-2012-3499)

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

915883 - CVE-2012-3499 httpd: multiple XSS flaws due to unescaped hostnames
915884 - CVE-2012-4558 httpd: XSS flaw in mod_proxy_balancer manager interface
953729 - CVE-2013-1862 httpd: mod_rewrite allows terminal escape sequences to be written to the log file
