CVE-2014-2064

Estado: ModificadaMedia (5)—💥 PoC

La función loadUserByUsername en hudson/security/HudsonPrivateSecurityRealm.java en Jenkins en versiones anteriores a 1.551 y LTS en versiones anteriores a 1.532.2 permite a atacantes remotos determinar si existe un usuario relacionado con los intentos de acceso fallidos.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
