CVE-2022-1704Network attack vector

Data disclosure via unprotected backup XML parsing

Published Aug 5, 2022 · Updated Apr 16, 2025

XXE in Inductive Automation Ignition 8.1 before 8.1.8 and 7.9 before 7.9.21 allows remote authenticated users to disclose confidential data. A crafted Gateway backup ZIP embeds external entities in backupinfo.xml, which the restore parser processes without XML security flags. Exploitation requires config-level access or a trusted config user to restore the archive, enabling data disclosure, SSRF, port scans, or a service interruption.
