Name of the Vulnerable Software and Affected Versions XINJE XD/E Series PLC Program Tool versions up to v3.5.1

Description A vulnerability exists that can allow an authenticated, local attacker to load a malicious DLL, requiring local access and sufficient file-write privileges to exploit. If exploited, the attacker could place a malicious DLL file on the system, allowing them to execute arbitrary code with the privileges of another user's account.
