CVE-2025-7073 — Local Privilege Escalation via Arbitrary File Operation in Bitdefender Total Security

A local privilege escalation vulnerability in Bitdefender Total Security versions prior to 27.0.47.241 allows low-privileged attackers to elevate privileges. The issue arises from bdservicehost.exe deleting files from a user-writable directory (C:\ProgramData\Atc\Feedback) without proper symbolic link validation, enabling arbitrary file deletion. This issue is chained with a file copy operation during network events and a filter driver bypass via DLL injection to achieve arbitrary file copy and code execution as elevated user.
