Technical details

A SQL injection vulnerability exists in Chamilo LMS 2.0.0-RC.2 within the 'users_active' action of the statistics AJAX endpoint (public/main/inc/ajax/statistics.ajax.php). The 'date_start' and 'date_end' parameters are directly interpolated into a SQL query without sanitization or parameterized queries. This represents an incomplete fix for a previous vulnerability (CVE-2026-30881), where sanitization was applied to one action but missed in another within the same file. An authenticated attacker with administrative privileges can exploit this via network requests to perform time-based blind SQL injection, allowing for arbitrary data extraction from the database. The issue is resolved in version 2.0.0.
