WibuKey Runtime 6.51 contains an unquoted service path vulnerability in the WkSvW32.exe service that enables local privilege escalation. Attackers can exploit the unquoted path 'C:\PROGRAM FILES (X86)\WIBUKEY\SERVER\WkSvW32.exe' to inject malicious executables. This vulnerability allows local attackers to potentially execute arbitrary code with elevated privileges. The flaw affects the WibuKey licensing software commonly used for software protection and licensing management.
