Estado: ModificadaAlta (8.8)—💥 Exploit

A privilege escalation vulnerability in Nagios XI 5.2.x through 5.4.x before 5.4.13 allows an attacker to leverage an RCE vulnerability escalating to root.

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.
