Executive Summary

This vulnerability is a stored cross-site scripting (XSS) issue found in Movable Type's Export Sites feature. An attacker can input specially crafted data that gets stored by the system. When a logged-in user accesses the affected part of the application, the malicious script executes in their web browser.

This means that the attacker can run arbitrary scripts on the victim's browser, potentially leading to unauthorized actions or data exposure.

The vulnerability affects Movable Type versions 7 series and 8.4 series, which are already End-of-Life (EOL).

Impact Analysis

This stored cross-site scripting vulnerability can impact you by allowing attackers to execute arbitrary scripts in the browsers of logged-in users.

  • It can lead to theft of user credentials or session tokens.
  • It may enable attackers to perform actions on behalf of the user without their consent.
  • It can result in unauthorized access to sensitive information.
