ZDI-26-832: AVG Internet Security avg Tools Svc Link Following Local Privilege Escalation Vulnerability
Summary: ZDI-26-832 describes a local privilege escalation flaw in AVG Internet Security's avgToolsSvc service, where an attacker who can already run low-privileged code creates a symbolic link to abuse the service into deleting a folder. Exploitation lets the attacker escalate privileges and execute arbitrary code as SYSTEM, and the issue is fixed in AVG version 26.5.
What you should know: The flaw requires only low-privileged code execution to start, then hands the attacker SYSTEM rights on a machine running security software - so any foothold on an endpoint running an unpatched AVG build can become full control of the host.
