AI-powered analysis for quick understanding

An attacker can upload a specially crafted CSV file that contains malicious code, which can then execute JavaScript when viewed by administrators or users who can access import logs. This vulnerability affects versions prior to 1.11.30 and relies on the attacker being able to upload files with unsafe names.

Technical Description

Chamilo is a learning management system. Prior to version 1.11.30, a stored cross-site scripting (XSS) vulnerability exists due to insufficient sanitization of CSV filenames. An attacker can upload a maliciously named CSV file (e.g., <img src=q onerror=prompt(8)>.csv) that leads to JavaScript execution when viewed by administrators or users with access to import logs or file views. This issue has been patched in version 1.11.30.
