C2 WebResource web interface XSS vulnerability

Original Release date: 03 Apr 2013 | Last revised: 24 Jul 2014

Overview

The C2 WebResource web interface contains a XSS vulnerability.

Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

The C2 WebResource web interface is vulnerable to XSS on the following URL and parameter:
https://c2webresource/fileview.asp?File=<script>alert(document.cookie)</script>

Impact

An attacker with access to the C2 WebResource web interface can conduct a cross-site scripting attack, which may be used to result in information leakage, privilege escalation, and/or denial of service.

Solution

We are currently unaware of a practical solution to this problem.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS, CSRF, or SQLi attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the C2 WebResource web interface using stolen credentials from a blocked network location.
