Potential Exploitation of an Unquoted Service Path Vulnerability
editPotential Exploitation of an Unquoted Service Path Vulnerability
editAdversaries may leverage unquoted service path vulnerabilities to escalate privileges. By placing an executable in a higher-level directory within the path of an unquoted service executable, Windows will natively launch this executable from its defined path variable instead of the benign one in a deeper directory, thus leading to code execution.
