CVE-2023-54353 Personifyinc CVE debrief

Who should care

Organizations using Chromacam 4.0.3.0 should prioritize patching or mitigating this vulnerability. Local attackers with write access to certain directories can exploit this vulnerability to execute code with elevated privileges. This vulnerability is particularly concerning for environments where attackers may already have local access or where directory permissions are not tightly controlled.

Technical summary

The PsyFrameGrabberService in Chromacam 4.0.3.0 has an unquoted service path vulnerability. This allows local attackers to execute arbitrary code by placing malicious executables in directories with unquoted paths, such as C: or C:Program Files (x86)Personify. When the PsyFrameGrabberService starts automatically at boot, it will execute the malicious file with LocalSystem privileges. The vulnerability is classified under CWE-428 (Unquoted Service Path).
