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.\n\n## Affected\n\n- `antivirus < 30.0.25.77`\n- `antivirus_plus < 27.0.47.241`\n- `endpoint_security_tools < 7.9.20.515`\n- `internet_security < 27.0.47.241`\n- `total_security < 27.0.47.241`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `antivirus 30.0.25.77`\n- `antivirus_plus 27.0.47.241`\n- `endpoint_security_tools 7.9.20.515`\n- `internet_security 27.0.47.241`\n- `total_security 27.0.47.241`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
