Apache mod_proxy_ftp Undefined Charset UTF-7 XSS Vulnerability
------------------------------------------------------------------------
SUMMARY
The Apache HTTP Server Project is "an effort to develop and maintain an
open-source HTTP server for modern operating systems including UNIX and
Windows NT. The goal of this project is to provide a secure, efficient and
extensible server that provides HTTP services in sync with the current
HTTP standards.
Apache has been the most popular web server on the Internet since April
1996. The November 2005 Netcraft Web Server Survey found that more than
70% of the web sites on the Internet are using Apache, thus making it more
widely used than all other web servers combined".
<http://httpd.apache.org/docs/2.2/mod/mod_proxy_ftp.html> Mod_proxy_ftp
"provides support for the proxying FTP sites. Note that FTP support is
currently limited to the GET method." A XSS(UTF7) exist in mod_proxy_ftp.c
Charset is not defined and we can provide XSS attack using ";" char in
URL by setting Charset to UTF-7.
