CVE-2024-13960

Estado: AplazadaAlta (7.8)—

Link Following Local Privilege Escalation Vulnerability in TuneUp Service in AVG TuneUp Version 23.4 (build 15592) on Windows 10 allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via creating a symbolic link and leveraging a TOCTTOU (time-of-check to time-of-use) attack.

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:L/PR:L sin UI permite escalada local. Symbolic link (CWE-59) y TOCTTOU (CWE-367) ejecutan código arbitrario como SYSTEM desde contexto de usuario con privilegios.

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.
