Cherokee Web Server does not adequately validate user input thereby allowing directory traversal

Vulnerability Note VU#464827

Original Release Date: 2002-09-24 | Last Revised: 2002-09-24

Overview

Cherokee contains a directory traversal vulnerability caused by failure to filter '../' character sequences.

Description

Cherokee is a compact, open-source web server. Cherokee does not filter '../' sequences from HTTP requests. As a result, it is possible for a remote attacker to request and read files outside the Cherokee HTTP root directory.

Impact

Attackers may read any file on the filesystem that is readable by the Cherokee process, which may be running as root.

Solution

The CERT/CC is currently unaware of a practical solution to this problem.
