Estado: RecibidaMedia (5.3)—

Frappe HR (hrms) anterior a 16.11.0, incluidas todas las versiones 14.x y 15.x hasta 15.64.3, contiene una vulnerabilidad de autorización faltante en el método expire_allocation incluido en la lista blanca que permite a usuarios autenticados hacer expirar cualquier asignación de vacaciones. Los atacantes sin roles de HR pueden nombrar la asignación de vacaciones de otro empleado en una solicitud POST para poner a cero sus vacaciones asignadas y borrar el saldo de vacaciones restantes de ese empleado.

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.

Acceso remoto autenticado (PR:L) a servicio sin validación de autorización (CWE-862). Modificación de datos de empleados (leave allocation) y potencial escalada de privilegios funcional sin roles HR requeridos.

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.
