CVE-2026-7557

Estado: AnalizadaCrítica (9.1)—

An improper verification of cryptographic signature vulnerability in the SAML authentication module of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows an unauthenticated remote attacker to bypass authentication and impersonate any user, including administrators. This vulnerability affects deployments with SAML single sign-on 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.

Vector CVSS red sin autenticación (AV:N PR:N UI:N) indica T1190. La vulnerabilidad de firma criptográfica en SAML permite bypass de autenticación e impersonación (T1078.002: acceso a credenciales/cuentas válidas) y manipulación del control de acceso SAML (T1556.007).

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.
