JFrog Artifactory (Self Hosted) versions before 7.133.11 are vulnerable to a privilege escalation attack due to a validation check of the token signature/issuer and not the token’s scope.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Escalada de privilegios en servicio remoto (Artifactory) por validación débil de tokens; acceso con privilegios elevados permite ejecución de comandos en el contexto del servicio.

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.
