CVE-2026-35149

Estado: AnalizadaAlta (8.2)—

HCL DFXServer is affected by an Authentication Bypass vulnerability via server response manipulation. An unauthorized user without valid credentials can exploit this flaw by intercepting and altering the server's authentication responses, allowing them to gain unauthorized access to the application without verification.

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 explotación remota sin autenticación (T1190). La manipulación de respuestas del servidor permite acceso no autorizado (CWE-294: Authentication Bypass), resultando en T1078 (Acceso válido con credenciales falsas/obtenidas).

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.
