Date Published:	19 Sep 2008
Severity:	Medium
Last Updated:	Tuesday 01 January, 2008
Source:	Secunia Advisory: SA31384
Industry Reference:	CVE-2008-2939 US-CERT VU#663763
Protection Provided by:
Who is Vulnerable?	Apache Software Foundation HTTP Server 2.0.63 and prior Apache Software Foundation HTTP Server 2.2.9 and prior
Vulnerability Description	A cross site scripting vulnerability exists in Apache web server mod_proxy_ftp module. The Apache HTTP server is the most popular web server used on the Internet. The Apache mod_proxy_ftp module allows the Apache web server to act as a proxy for FTP sites.  The mod_proxy_ftp module fails to properly sanitize user-supplied input. By supplying a crafted FTP URL, a remote attacker may be able to execute arbitrary Javascript in the context of a site being proxied by the Apache server. This may allow an attacker to steal cookies (including authentication cookies) and launch other attacks.
Update/Patch Avaliable	Apache has released updates to address this issue: http://svn.apache.org/viewvc?view=rev&revision=682868 http://svn.apache.org/viewvc?view=rev&revision=682868 http://svn.apache.org/viewvc?view=rev&revision=682871
Vulnerability Details	The flaw is due to improper globbing on the part of the mod_proxy_ftp module. Apache Filename globbing is the process of using wildcards to match filenames. The mod_proxy_ftp module fails to properly filter globbed characters in FTP URIs. Successful exploitation would result in compromise of target user’s cookies associated with the site and modification of user information.
