CVE-2025-40536

Estado: AnalizadaCrítica (9.8)⚠ Explotación activa

SolarWinds Web Help Desk was found to be susceptible to a security control bypass vulnerability that if exploited, could allow an unauthenticated attacker to gain access to certain restricted functionality.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

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

Vector AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). CWE-693 (security control bypass) permite acceso no autenticado a funcionalidad restringida, comprometiendo confidencialidad, integridad y disponibilidad. KEV activo con ransomware sugiere ejecución remota y manipulación post

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.
