Estado: AplazadaAlta (8.5)—

Comodo Chromodo Browser 52.15.25.664 contains an unquoted service path vulnerability in the ChromodoUpdater service that runs 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 de escalada de privilegios (AV:L, PR:L) en servicio SYSTEM de Comodo Chromodo. La ruta sin comillas (CWE-428) permite inyectar ejecutable malicioso que se ejecuta con máximos privilegios al reiniciar, logrando ejecución de código arbitrario (T1059) con elevación (T1548).

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.
