If a local attacker places a malicious DLL in such a directory and an administrator subsequently runs the tool, the malicious DLL is loaded into the elevated process and executes with Administrator/SYSTEM privileges.","published":"2026-09-01T14:17:49.893","modified":"2026-09-01T14:17:49.893","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.rockwellautomation.com/en-us/trust-center/security-advisories/advisory.SD1800.html"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-01T14:17:49.893"}}
