CVE-2022-1356

Estado: ModificadaAlta (7.8)—

cnMaestro is vulnerable to a local privilege escalation. By default, a user does not have root privileges. However, a user can run scripts as sudo, which could allow an attacker to gain root privileges when running user scripts outside allowed commands.

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).
