Local privilege escalation via symbolic-link file operations
Published Dec 10, 2025 · Updated Dec 10, 2025
Local privilege escalation in Bitdefender consumer security products before 27.0.47.241 allows local users to execute code as an elevated user. bdservicehost.exe follows symbolic links while deleting files in the user-writable C:\ProgramData\Atc\Feedback directory, enabling arbitrary file deletion. Exploitation requires low-privileged local access and chains a network-event file copy with DLL injection that bypasses a filter driver.
