Script execution via undisclosed blog and announcement inputs

Published Jan 30, 2020 · Updated Aug 6, 2024

Cross-site scripting in blog.php and announcements.php in Chamilo LMS 1.9.4 allows remote attackers to inject script or HTML. The published records identify the affected scripts but do not disclose the input fields, persistence behavior, or missing validation or encoding operation. Exploitation requires a user to render attacker-controlled content; successful script execution can read or alter browser-accessible data in that user's session.
