Description: A vulnerability was reported in Apache mod_proxy_ftp. A remote user can conduct cross-site scripting attacks.
The mod_proxy_ftp module does not properly filter HTML code from UTF-7 character set user-supplied input before displaying the input.
A remote user can create a specially crafted URL 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.
