Name of the Vulnerable Software and Affected Versions: Bosch Monitor Wall versions up to and including 10.00.0164

Description: The issue allows an attacker to execute arbitrary code on a victim's system by loading a DLL through an uncontrolled search path element in the Bosch Monitor Wall installer. This can happen if the victim is tricked into placing a malicious DLL in the same directory where the installer is started from.

Recommendations: For versions up to and including 10.00.0164, ensure that no malicious DLLs are placed in the directory where the installer is run to prevent arbitrary code execution. As a temporary workaround, consider restricting the execution of the installer to trusted directories only.
