Unquoted Service Path in ChromaCam 4.0.3.0

Executive Summary

CVE-2023-54353 is an unquoted service path vulnerability found in Chromacam version 4.0.3.0, specifically in the PsyFrameGrabberService. This vulnerability allows local attackers who have write access to certain directories on the system, such as C:\ or C:\Program Files (x86)\Personify\, to place malicious executable files. Because the service path is unquoted, the system may execute these malicious files with LocalSystem privileges when the service starts automatically at boot, enabling arbitrary code execution.

Impact Analysis

This vulnerability can have a significant impact because it allows an attacker with local write access to execute arbitrary code with LocalSystem privileges. This means the attacker can gain full control over the affected system, potentially leading to unauthorized access, data theft, system manipulation, or further malware installation.

Detection Guidance

This vulnerability can be detected by checking for unquoted service paths related to the PsyFrameGrabberService in Chromacam 4.0.3.0 or earlier versions. Specifically, you should inspect the service path for unquoted spaces that could allow execution of malicious executables placed by an attacker.

On a Windows system, you can use the following command to check the service path for PsyFrameGrabberService:

• sc qc PsyFrameGrabberService

Look for unquoted paths in the output, especially paths containing spaces without surrounding quotes. Additionally, check for suspicious executable files named Program.exe or PsyFrameGrabberService.exe in directories like C:\ or C:\Program Files (x86)\Personify\ which could indicate exploitation attempts.

Mitigation Strategies

To mitigate this vulnerability, immediately restrict write access to the directories involved, such as C:\ and C:\Program Files (x86)\Personify\, to prevent attackers from placing malicious executables.

Additionally, update Chromacam to a version later than 4.0.3.0, as the vulnerability exists in version 4.0.3.0 and earlier. If an update is not available, manually correct the service path by quoting it properly to prevent execution of malicious files.

Finally, monitor the system for suspicious files named Program.exe or PsyFrameGrabberService.exe in the affected directories and remove any unauthorized files.
