Active Webcam 115 Unquoted Service Path Patched «FHD 2027»

Because the default installation directory is usually C:\Program Files (x86)\Active Webcam\ , the path inherently contains spaces. Without proper quotation marks in the Windows Registry entry, the application left systems vulnerable to local privilege escalation (LPE). How the Vulnerability is Exploited

The phrase indicates that the vulnerability has been remediated, either through an official vendor update, an administrative script, or manual registry intervention. 1. The Official Vendor Fix

: A local attacker with limited privileges can place a malicious executable in a parent directory (like C:\Program.exe ). When the service restarts, Windows may execute the malicious file instead of the intended program, potentially granting the attacker administrative (SYSTEM) privileges .

Ensure that standard users do not have write permissions to the folders C:\Program Files or the specific Active Webcam 115 installation folder. Conclusion

C:\Program Files\Active WebCam\webcam.exe active webcam 115 unquoted service path patched

The most direct way to this is to fix the registry entry: Open regedit (Registry Editor).

Windows interprets unquoted paths with spaces as potential execution points. For example, it will attempt to execute files in this order: C:\Program.exe C:\Program Files\Active.exe C:\Program Files\Active WebCam\WebCam.exe

sc config "ActiveWebCam" binPath= "\"C:\Program Files\Active WebCam\webcam.exe\""

C:\Program Files\Active Webcam\awservice.exe Ensure that standard users do not have write

Later builds and patches for Active Webcam addressed this during the installation process. The installer script was updated to ensure that when the service is registered with the OS, the string is passed with the correct formatting. 3. Automated Remediation

: Comprehensive vulnerability metadata and reference list available at Remediation & Patching

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

For example, consider the following unquoted service path: C:\Program Files\Active Webcam\webcam.exe "C:\\Program Files\\Active Webcam\\SimvWebcam.exe"

sc qc "Active Webcam Service"

Compare your file version vs. vendor release notes. Run the sc qc command as shown above.

CreateService(..., "C:\\Program Files\\Active Webcam\\SimvWebcam.exe", ...)
