Administrators can check for this vulnerability by running the following command in a Windows Command Prompt:
With SYSTEM access, the attacker can disable antivirus, dump credentials from LSASS, install persistent backdoors, or move laterally across the network.
After the change, restart the service:
The attacker creates a reverse shell executable named Active.exe and places it in C:\Program Files (x86)\ . They also may create Program.exe in C:\ .
Notice the problem immediately? The service path contains and no quotes :
wmic service get name,displayname,pathname,startmode | findstr /i "auto" | findstr /i /v "C:\Windows\\" | findstr /i /v """ Use code with caution.
In the realm of Windows endpoint security, certain misconfigurations act as silent backdoors, patiently waiting for an attacker with low-level privileges to exploit them. One such classic privilege escalation vector is the vulnerability. When paired with a legitimate piece of software like Active Webcam 11.5 —a popular tool for turning a PC into a network-accessible security camera—this oversight can transform a benign monitoring tool into a launchpad for full system compromise.
Active Webcam, a popular software used for capturing and streaming video content, has been found to have a critical vulnerability in its 11.5 version. The vulnerability, known as an unquoted service path, has raised concerns among cybersecurity experts and users alike. In this article, we will delve into the details of this vulnerability, its implications, and the necessary steps to take to mitigate the risk.
