Attack-Flow Graph

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Request Tracker software's calendar invitation parsing feature. It occurs because the software displays invitation data without properly sanitizing HTML content. An attacker can exploit this by sending a specially crafted email that contains malicious JavaScript code. When the ticket is viewed by a logged-in user, the malicious code executes in their browser context.

Impact Analysis

The vulnerability can allow attackers to execute arbitrary JavaScript code in the context of a logged-in user. This can lead to unauthorized actions such as stealing session cookies, performing actions on behalf of the user, or delivering further malicious payloads, potentially compromising user accounts and data.
