Unidomedia Chameleon LE/Pro Directory Traversal
Date of Advisory:
-----------------
July 20th 2006
Product:
--------
Chameleon LE <= 1.203
Chameleon Pro is suspected to be vulnerable but since I am cheap and not about
to pay $99 for
the pro version to check if a bug exists I CAN NOT
confirm that the Pro version is vulnerable but can assume since it shares most
of the same code.
Vendor:
-------
Unidomedia

Exploit or Vulnerability:
-------------------------
There is a directory traversal vulnerabilities in index.php
The vulnerability is at line 34: include "chd_ads/$_GET[rmid]";
The user can pass a directory traversal attack to index.php?rmid= and can load
ANY file on the server that the attacker has read access to. This can lead to a
user gaining information such as server usernames from the passwd file or
reading other website files which could lead to vulnerable information being
accessed.
