CVE-2016-20090

Estado: AplazadaAlta (8.5)—

Comodo Dragon Browser versions up to 52.15.25.663 contain a privilege escalation vulnerability in the DragonUpdater service due to an unquoted service path running with SYSTEM privileges. A local attacker can insert a malicious executable in the service path and execute arbitrary code with elevated privileges upon service restart or system reboot.

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 local (AV:L, PR:L) en servicio SYSTEM con ruta sin entrecomillar; permite insertar ejecutable malicioso para ejecución arbitraria de código elevado.

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.
