CVE-2023-2746Network attack vector

Remote access via permissive CORS API

Published Jul 11, 2023 · Updated Nov 7, 2024

Cross-Site Request Forgery in the Enhanced HIM API in Rockwell Automation Enhanced HIM v1.001 allows remote attackers to disclose data via malicious links. The API accepts cross-origin requests because its CORS protection is insufficient, allowing a forged request to operate with the user's authenticated context. Exploitation requires a user to click an untrusted link or a successful XSS attack and can expose sensitive information or provide full remote access.
