Estado: AnalizadaAlta (8.7)—

Joomla com_booking component 2.4.9 contains an information disclosure vulnerability that allows unauthenticated attackers to enumerate user accounts by exploiting the getUserData function in the customer controller. Attackers can send GET requests to index.php with option=com_booking, controller=customer, task=getUserData, and an id parameter to retrieve user names, usernames, and email addresses through brute force enumeration.

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.

Vector CVSS AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-203 + enumeración de cuentas de usuario sustentan impacto T1087.001 (Account Discovery).

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.
