Technical details
A local privilege escalation vulnerability exists in the NoMachine Device Server due to an uncontrolled search path element (CWE-427). The application attempts to load a library from an unsecured location, which can be manipulated by a local user. An attacker with low-privileged code execution capabilities on the target system can place a malicious DLL or library in the expected path. When the service loads the library, it executes the attacker's code with SYSTEM-level privileges. This vulnerability is addressed in NoMachine version 9.4.14.
