Name of the Vulnerable Software and Affected Versions Total Defense Anti-virus version 9.0.0.773

Description The issue concerns insecure access control for a specific directory used by the AMRT.exe process, allowing local attackers to hijack the bdcore.dll file. This leads to privilege escalation when the AMRT service loads the DLL.
