Attack-Flow Graph

Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue in the Movable Type software, specifically in the Edit CategorySet of the ContentType page. An attacker with 'ContentType Management' privileges can store malicious script input, which will then execute in the web browser of any user who accesses that page.

Impact Analysis

The vulnerability can lead to arbitrary script execution in the browsers of users who visit the affected page, potentially allowing attackers to steal session tokens, perform actions on behalf of users, or compromise user data. However, exploitation requires the attacker to have 'ContentType Management' privileges and user interaction to trigger the script.
