An issue in ralphje Signify before v.0.9.2 allows a remote attacker to escalate privileges via the signed_data.py and the context.py components

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.

Vector CVSS: AV:N/AC:L/PR:L indica acceso remoto con privilegios, precedencia T1210. CWE-269 (improper access control) y descripción de escalada de privilegios → T1068 como impacto primario.

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.
