CVE-2025-64131

Estado: AnalizadaAlta (7.5)—

Jenkins SAML Plugin 4.583.vc68232f7018a_ and earlier does not implement a replay cache, allowing attackers able to obtain information about the SAML authentication flow between a user's web browser and Jenkins to replay those requests, authenticating to Jenkins as that user.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.47%
Percentil entre todas las CVEs puntuadas: 39
Fecha de la puntuación: 6/10/2026

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.

ExplotaciónT1203 Exploitation for Client Executionexecution85 %
Impacto principalT1078 Valid Accountsstealth · persistence · privilege escalation · initial access80 %
Impacto secundarioT1556 Modify Authentication Processdefense impairment · persistence · credential access65 %

UI:R (interacción del usuario) y vector de red dictan T1203. El atacante obtiene autenticación SAML válida (T1078) al capturar y reproducir mensajes SAML; la falta de replay cache permite usurpar cuentas de usuario.

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.
