Estado: AnalizadaAlta (8.1)—

IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.8 is vulnerable to a privilege escalation when using Liberty collectives.

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.

Acceso remoto con PR:L en red, escalada de privilegios explícita en Liberty collectives. AV:N/PR:L sin UI mapea a T1210; impacto es escalada (T1068) por privilegios de administrador/root.

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.
