CVE-2026-49188

Estado: AnalizadaAlta (8.7)—

The ai_cmd utility executes with full root permissions. It pipes socket inputs directly to popen(), paving the way for unauthenticated users to execute arbitrary root 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).

🎯 Técnicas ATT&CK

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

AV:A (red adyacente) sin autenticación (PR:N) permite ejecutar comandos arbitrarios con permisos root mediante popen() en ai_cmd. Ejecución de comandos y escalada de privilegios confirmadas por el texto.

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.
