If a malicious user has write permissions to the root directory ( C:\ ) or the C:\Program Files\ directory, they can place a malicious executable named Program.exe or Active.exe there. The next time the service restarts or the system boots, Windows will execute the malicious file instead of the legitimate service, often granting the attacker elevated system privileges. Case Study: Active Webcam 115
Resolving this vulnerability requires wrapping the executable path in double quotes within the Windows Registry. This tells the Windows Service Control Manager exactly where the string ends, preventing it from parsing spaces as breaks. Method 1: Remediation via Windows Registry (Manual)
Double-click ImagePath and modify the value to include double quotes around the path. Click and close the Registry Editor. Method 2: Command Line Patching active webcam 115 unquoted service path patched
An unquoted service path vulnerability occurs when a service executable path contains spaces and is not enclosed within quotation marks.
For automated patch management across multiple endpoints, a PowerShell script can read the current path, wrap it in quotes, and update the service property directly: powershell If a malicious user has write permissions to
As the cybersecurity community continues to battle both sophisticated zero-days and simple misconfigurations, the unquoted service path remains a powerful reminder that sometimes, the most dangerous bugs are the easiest to fix.
– An attacker with local access to a Windows system running Active WebCam 11.5 checks the service configuration using tools like sc qc ACTIVEWEBCAM or by inspecting the registry. This tells the Windows Service Control Manager exactly
"C:\Program Files\Active Webcam\awcservice.exe" (Quotes present) How to Apply the Patch
If ACTIVEWEBCAM appears in the list with an unquoted path, it requires a manual fix. Step 2: Apply the Registry Fix Press Win + R , type , and press Enter.
The configuration for Active Webcam's service resides in the registry under the SYSTEM\CurrentControlSet\Services hive. To patch it manually: Open the Registry Editor ( regedit.exe ).
