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.
Integer Overflow or Wraparound vulnerability in Avast Antivirus (25.1.981.6) on Windows allows Privilege Escalation.This issue affects Antivirus: from 25.1.981.6 before 25.3.
Double fetch in sandbox kernel driver in Avast/AVG Antivirus <25.3 on windows allows local attacker to escalate privelages via pool overflow. Rated critical severity (CVSS 9.9), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
