WibuKey Runtime 6.51 contains an unquoted service path vulnerability in the WkSvW32.exe service that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted path in 'C:\PROGRAM FILES (X86)\WIBUKEY\SERVER\WkSvW32.exe' to inject malicious executables and escalate privileges.

In the WibuKey driver for Windows below Version 6.72, insufficient validation of user input when calculating the size of a kernel buffer could cause small amounts of data to be written outside the intended kernel buffer. This can lead to a system crash. Under unfavorable circumstances, adjacent kernel memory may be modified.

This vulnerability allows local attackers to escalate privileges on affected installations of Wibu-Systems WibuKey Runtime. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 8.8.
