MEDIUMChamilo LMS < 1.11.30 - Stored Cross-Site Scripting via CSV Filename
Title source: llmDescription
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.
