Estado: AplazadaAlta (7.8)—

Link Following Local Privilege Escalation Vulnerability in TuneupSvc.exe in AVG TuneUp 24.2.16593.9844 on Windows allows local attackers to escalate privileges and execute arbitrary code in the context of SYSTEM via creating a symbolic link and leveraging the service to delete a directory

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/UI:N indica escalada de privilegios local. El vector CVSS y descripción confirman explotación de enlace simbólico (CWE-59) para ejecutar código arbitrario como SYSTEM desde contexto 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.
