GHSA-9247-4234-VWRQ

Vulnerability from github – Published: 2025-12-10 12:31 – Updated: 2025-12-10 12:31

Details

A local privilege escalation vulnerability in Bitdefender Total Security 27.0.46.231 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.

Severity ?

8.8 (High)
