CVE-2021-47974

Estado: AplazadaAlta (8.5)—

VX Search 13.5.28 contains an unquoted service path vulnerability in both VX Search Server and VX Search Enterprise services that allows local attackers to escalate privileges. Attackers can place malicious executables in unquoted path directories like C:\Program Files\VX Search to execute arbitrary code with LocalSystem privileges when services restart.

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:L/PR:L indica acceso local con privilegios bajos. CWE-428 (unquoted service path) permite escalada de privilegios local. Attackers place malicious executables para ejecutar código arbitrario con privilegios LocalSystem.

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.
