Security Issue Details

Rockwell Automation uses the latest version of the CVSS scoring system to assess thesecurity issues. The security of our products is important to us as your industrial automation supplier.  This issue was found internally during routine testing and is being reported based on our commitment to transparency and to improvement of all business environments.

CVE-2023-2746 IMPACT
The API that the application uses is not protected sufficiently and uses incorrect Cross-Origin Resource Sharing (CORS) settings. As a result, it is vulnerable to a Cross Site Request Forgery (CSRF) attack. To use this, a threat actor would have to convince a user to click on an untrusted link. This is done through a social engineering attack or by performing a Cross Site Scripting Attack (XSS). Using a CSRF could lead to sensitive information disclosure and full remote access to the affected products.
