Estado: AnalizadaAlta (7.5)—

HCL Connections Docs may mishandle validation of certain uploaded documents leading to denial of service due to resource exhaustion.

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.

AV:N/PR:N/UI:N indica red sin privilegios (T1190). CWE-405 (validation error) + descripción de exhaustión de recursos por documentos mal validados sugieren ataque de denegación de servicio (T1499.004).

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.
