CVE-2018-25122

Estado: AnalizadaAlta (8.7)—

Nagios XI versions prior to 5.4.13 contain a remote code execution vulnerability in the Component Download page. The download/import handler used unsafe command construction with attacker-controlled input and lacked sufficient validation and output encoding, allowing an authenticated user to inject commands or otherwise execute arbitrary code with the privileges of the application service.

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.

Vulnerabilidad en servicio remoto (Nagios XI) que requiere autenticación (PR:L) y permite inyección de comandos (CWE-78). El atacante autenticado ejecuta código arbitrario con privilegios 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.
