Lifecycle Timeline
2DescriptionCVE.org
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.
AnalysisAI
Bitdefender Total Security, Antivirus, Internet Security, and Endpoint Security Tools prior to version 27.0.47.241 allow local attackers with low privileges to execute arbitrary code as SYSTEM through a complex attack chain. The bdservicehost.exe service deletes files from C:\ProgramData\Atc\Feedback without validating symbolic links (CWE-59), enabling arbitrary file deletion that attackers chain with network-triggered file copy operations and filter driver bypass via DLL injection to achieve full privilege escalation. EPSS indicates 0.02% exploitation probability (6th percentile), and no public exploit code or active exploitation has been identified at time of analysis. Vendor has released patches addressing this multi-stage local escalation vector.
