CVE Reference:
CVE-2008-2939
(Links to External Site)
|
Date: Dec 5 2008
|
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 prior to 2.2.10

Description:
A vulnerability was reported in Apache mod_proxy_ftp. A remote user can conduct cross-site scripting attacks.
The software does not properly filter HTML code from user-supplied input in FTP URLs before displaying the input. A remote user can create a specially crafted FTP URL containing wildcards that, when loaded by a target user, will 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.
Marc Bevand of Rapid7 reported this vulnerability.

Synopsis: Moderate: Red Hat Application Stack v2.2 security and enhancement update
Advisory ID: RHSA-2008:0966-02
Product: Red Hat Application Stack
Advisory URL: https://rhn.redhat.com/errata/RHSA-2008-0966.html
Issue date: 2008-12-04
CVE Names: CVE-2007-6420 CVE-2008-2364 CVE-2008-2939
=====================================================================
1. Summary:
Red Hat Application Stack v2.2 is now available. This update fixes several
security issues and adds various enhancements.
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 v2 for Enterprise Linux (v.5) - i386, noarch, x86_64
3. Description:
The Red Hat Application Stack v2.2 is an integrated open source application
stack, that includes Red Hat Enterprise Linux 5 and JBoss Enterprise
Application Platform (EAP) 4.2.
This erratum updates the Apache HTTP Server package to version 2.0.10 which
addresses the following security issues:
A flaw was found in the mod_proxy module. An attacker who has control of
a web server to which requests are being proxied could cause a limited
denial of service due to CPU consumption and stack exhaustion. (CVE-2008-2364)
A flaw was found in the mod_proxy_ftp module. Where Apache is configured
to support ftp-over-httpd proxying, a remote attacker could perform a
cross-site scripting attack. (CVE-2008-2939)
A cross-site request forgery issue was found in the mod_proxy_balancer
module. A remote attacker could cause a denial of service if
mod_proxy_balancer is enabled and an authenticated user is targeted.
(CVE-2007-6420)
The JBoss Enterprise Application Platform (EAP) 4.2 has been updated to
version 4.2.0.CP05.
The following packages were also updated:
* mysql to 5.0.60sp1
* mysql-connector-odbc to 3.51.26r1127
* perl-DBI to 1.607
* perl-DBD-MySQL to 4.008
* perl-DBD-Pg to 1.49
* php-pear to 1.7.2
