Cross-site scripting via unneutralized comment input

Published Dec 2, 2023 · Updated Oct 11, 2024

Cross-site scripting in Thecosy IceCMS 2.0.1 allows remote authenticated users to inject script through /planet user comments. The /planet user-comment handler fails to neutralize attacker-controlled comment input before including it in generated page content. Exploitation requires low-privileged access and a user to render the affected content, enabling attacker-supplied script to modify content in the browser.
