The vulnerability can be exploited by unauthenticated attackers to obtain cookies from logged-in users, allowing them to hijack a session of an administrative user. The theft of admin session cookies allows attackers to gain control over the FreePBX admin interface, enabling them to access sensitive data, modify system configurations, create backdoor accounts, and cause service disruption. This issue has been patched in version 16.0.68.39 for FreePBX 16 and version 17.0.18.38 for FreePBX 17.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

XSS reflejado en página HTTP expuesta (CWE-79, AV:N). El atacante roba cookies de sesión de admin (T1078.002) para hijackear la interfaz FreePBX, permitiendo ejecución de comandos del sistema y manipulación de configuraciones.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
