CVE-2023-53973

Estado: ModificadaAlta (8.5)—

Zillya Total Security 3.0.2367.0 contains a privilege escalation vulnerability that allows low-privileged users to copy files to unauthorized system locations using the quarantine module. Attackers can leverage symbolic link techniques to restore quarantined files to restricted directories, potentially enabling system-level access through techniques like DLL hijacking.

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 con AV:L/PR:L (acceso local con privilegios bajos) → T1068. Impacto: escalada de privilegios via DLL hijacking tras copiar archivos a directorios restringidos; también abusa de enlaces simbólicos (T1574 secuestro de carga de librerías).

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.
