CVE-2023-29030

Sensitive-data modification via cross-site scripting

Published May 11, 2023 · Updated Aug 2, 2024

Cross-site scripting in all Rockwell Automation ArmorStart ST firmware versions allows attackers to alter or interrupt its web page. Rockwell Automation has not disclosed which web-interface input accepts script content or how that content reaches an HTML response without neutralization. Exploitation requires user interaction, such as phishing, and exposure is limited when the device web server remains disabled by default; successful execution permits sensitive-data access or modification and can make the page unavailable.
