Title: Oracle MySQL Eventum 2.3 Remote Script Insertion Vulnerabilities
Advisory ID: ZSL-2011-4989
Type: Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 11.02.2011

Summary

Eventum is a user-friendly and flexible issue tracking system that can be used by a support department to track incoming technical support requests, or by a software development team to quickly organize tasks and bugs.

Description

Eventum suffers from a cross-site scripting vulnerability. The persistent (stored) XSS issue is triggered when input passed via the 'keywords' parameter to the list.php script is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. Or, you can trigger the issue when parsing the string '<script>alert(1)</script>' into the search box and it will be stored every time you navigate back to the list.php page. If there's no activity the stored string will self execute every 5 minutes. 'forgot_password.php' and 'select_project.php' are also vulnerable because they fail to perform filtering when using the REQUEST_URI variable.
