Estado: AnalizadaCrítica (9.8)—

SolarWinds Web Help Desk is found to be affected by a SAML authentication bypass vulnerability. This requires the SAML 2.0 authentication method to be enabled.

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.

SAML authentication bypass en app web sin privilegios requeridos (PR:N, UI:N, AV:N) permite acceso no autorizado; vector CVSS crítico (C:H, I:H, A:H) sugiere además manipulación de datos.

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.
