Name of the Vulnerable Software and Affected Versions: Stormshield Endpoint Security Evolution versions 2.0.0 through 2.0.2

Description: The issue concerns local administrators who can replace the Visual C++ runtime DLLs in %WINDIR%system32 with malicious ones, bypassing the intended defense.

Recommendations: For versions 2.0.0 through 2.0.2, consider restricting access to the %WINDIR%system32 directory to prevent local administrators from replacing the Visual C++ runtime DLLs with malicious ones. As a temporary workaround, monitor the Visual C++ runtime DLLs for any unauthorized changes until a patch is available.
