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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","score":7.3},"cwes":["CWE-427"],"references":["https://claroty.com/2022/05/11/blog-research-from-project-file-to-code-execution-exploiting-vulnerabilities-in-xinje-plc-program-tool/","https://claroty.com/2022/05/11/blog-research-from-project-file-to-code-execution-exploiting-vulnerabilities-in-xinje-plc-program-tool/"],"products":["xinje:xd\\/e_series_plc_program_tool"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2021-34606","score":0.00475,"percentile":0.41085,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
