Description:
Adrian Pastor and Amir Azam have discovered a vulnerability in Apache, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed via the HTTP method is not properly sanitised before being returned to the user when displaying a "413 Request Entity Too Large" error page. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
The vulnerability is confirmed in version 2.2.4 and reported in versions 2.0.46, 2.0.51, 2.0.55, 2.0.59, and 2.2.3. Other versions may also be affected.
NOTE: Exploiting the vulnerability might be dependent on the Flash player version installed on the target machine.

Solution:
Add a "ErrorDocument 413" statement to the Apache config file.
