Estado: ModificadaMedia (6.9)—💥 Exploit

pam_motd (también conocido como el módulo MOTD) en libpam-modules anterior a v1.1.0-2ubuntu1.1 en PAM en Ubuntu v9.10 y libpam-modules anterior v1.1.1-2ubuntu5 en PAM en Ubuntu v10.04 LTS permite a usuarios locales cambiar propiedades de ficheros arbitrarios mediante un ataque symlink en .cache en el directorio home del usuario, relacionados con "user file stamps" y el fichero motd.legal-notice

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.
