CVE-2022-1018

Local-file disclosure via unsafe XML entity resolution

Published Apr 1, 2022 · Updated Apr 16, 2025

XXE in ISaGRAF, Connected Components Workbench, and SIS Workstation allows attackers to disclose local files via a malicious solution file. A shared dynamic-link library unsafely resolves external XML entities while parsing the file, sending referenced local-file data to an attacker-controlled web server. Exploitation requires local user interaction and affects confidentiality only; no integrity or availability impact is reported.
