Acuity CMS 2.6.x <= Path Traversal Arbitrary File Access
1. OVERVIEW
Acuity CMS 2.6.x (ASP-based) versions are vulnerable to Path Traversal.
2. BACKGROUND
Acuity CMS is a powerful but simple, extremely easy to use, low
priced, easy to deploy content management system. It is a leader in
its price and feature class.
3. VULNERABILITY DESCRIPTION
The issue is due to the script, /admin/file_manager/browse.asp, not
properly sanitizing user input, specifically directory traversal style
attacks (e.g., ../../) supplied via the 'path' parameter. It would
allow the attacker to access arbitrary files outside of web root
directory.
4. VERSIONS AFFECTED
Tested with version 2.6.2.
5. PROOF-OF-CONCEPT/EXPLOIT
http://localhost/admin/file_manager/browse.asp?field=&form=&path=../../
6. SOLUTION
The Acunity CMS is no longer in active development.
It is recommended to user another CMS in active development and support.
