Authenticated script execution via unfiltered title parameter

Published Jun 27, 2023 · Updated Dec 4, 2024

Cross-site scripting in ESPCMS P8.18101601 allows remote authenticated users to execute script through the title parameter. The administrator panel's index.php processes the title value without filtering, allowing supplied markup to execute in a Flash-capable browser. Administrator access and user interaction in such a browser are required, limiting the consequence to script execution in the affected web context.
