Local access is required to successfully exploit this vulnerability. This means the potential attacker must have access to the system and sufficient file-write privileges. If exploited, the attacker could place a malicious DLL file on the system, that when running XINJE XD/E Series PLC Program Tool will allow the attacker to execute arbitrary code with the privileges of another user's account.","published":"2022-05-11T15:15:08.000Z","lastModified":"2026-06-17T03:56:13.000Z","status":"Modified","sourceIdentifier":"info@cert.vde.com","cvss":{"version":"3.1","score":7.3,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"},"cwe":["CWE-427"],"affected":["xinje/xd\\/e series plc program tool"],"epss":{"score":0.00475,"percentile":0.40802,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.47%).
