Estado: ModificadaCrítica (9.8)—💥 Exploit

Command injection in `/main/webservices/additional_webservices.php` in Chamilo LMS <= v1.11.20 allows unauthenticated attackers to obtain remote code execution via improper neutralisation of special characters. This is a bypass of CVE-2023-34960.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
