CVE-2023-29029Network attack vector

Admin-level interface tampering via undisclosed XSS input

Published May 11, 2023 · Updated Jan 24, 2025

Cross-site scripting in Rockwell Automation ArmorStart ST firmware allows remote authenticated users to alter its web interface and view user data. Rockwell Automation has not disclosed the affected page, input field, or operation that fails to neutralize attacker-controlled content. Exploitation requires network access and administrator privileges while the embedded web server is enabled; successful attacks can also interrupt the web page, and that server is disabled by default.
