(Red Hat Issues Fix) Apache mod_status Input Validation Hole Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1018392
SecurityTracker URL:  http://securitytracker.com/id/1018392
CVE Reference:   CVE-2006-5752   (Links to External Site)
Date:  Jul 13 2007
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 2.2.4
Description:   A vulnerability was reported in Apache HTTPD's mod_status. A remote user can conduct cross-site scripting attacks.

When ExtendedStatus is enabled and the server-status page is accessible, a remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Apache software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Browsers that perform charset detection are affected.

Stefan Esser reported this vulnerability.
Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Apache software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Solution:   Red Hat has released a fix.

The Red Hat advisory is available at:

                   Red Hat Security Advisory

Synopsis:          Moderate: httpd security update
Advisory ID:       RHSA-2007:0557-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2007-0557.html
Issue date:        2007-07-13
Updated on:        2007-07-13
Product:           Red Hat Application Stack
CVE Names:         CVE-2006-5752 CVE-2007-1863 CVE-2007-3304 
- ---------------------------------------------------------------------

1. Summary:

Updated Apache httpd packages that correct two security issues are now
available for Red Hat Application Stack.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Application Stack v1 for Enterprise Linux AS (v.4) - i386, x86_64
Red Hat Application Stack v1 for Enterprise Linux ES (v.4) - i386, x86_64

3. Problem description:

The Apache HTTP Server is a popular Web server.

A flaw was found in the Apache HTTP Server mod_status module. On sites
where the server-status page is publicly accessible and ExtendedStatus is
enabled, this flaw could lead to a cross-site scripting attack. On Red Hat
Enterprise Linux, the server-status page is not enabled by default and it
is best practice to not make this publicly available. (CVE-2006-5752)

A bug was found in the Apache HTTP Server mod_cache module. On sites where
caching is enabled, a remote attacker could send a carefully crafted
request that would cause the Apache child process handling that request to
crash. This could lead to a denial of service if using a threaded
Multi-Processing Module. (CVE-2007-1863)

The Apache HTTP Server did not verify that a process was an Apache child
process before sending it signals. A local attacker with the ability to run
scripts on the Apache HTTP Server could manipulate the scoreboard and cause
arbitrary processes to be terminated which could lead to a denial of
service. (CVE-2007-3304).

Users of httpd should upgrade to these updated packages, which contain
backported patches to correct these issues. Users should restart Apache
after installing this update.

4. Solution:

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

This update is available via Red Hat Network.  Details on how to use 
the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/FAQ_58_10188

5. Bug IDs fixed (http://bugzilla.redhat.com/):

244658 - CVE-2007-1863 httpd mod_cache segfault
