TotalAV 5.15.69 contains an unquoted service path vulnerability in multiple system services running with LocalSystem privileges. Attackers can place malicious executables in specific unquoted path segments to potentially gain SYSTEM-level access by exploiting the service path configuration.
TotalAV 2020 4.14.31 has a quarantine flaw that allows privilege escalation. Exploitation uses an NTFS directory junction to restore a malicious DLL from quarantine into the system32 folder.
An issue was discovered in TotalAV v4.1.7. An unprivileged user could modify or overwrite all of the product's files because of weak permissions (Everyone:F) under %PROGRAMFILES%, which allows local users to gain privileges or obtain maximum control over the product.
