Rockwell Automation FactoryTalk® Services Platform FTSP - Weak Authentication via JWT Validation Bypass

A security issue exists within FactoryTalk® Services Platform (FTSP), allowing an attacker to bypass JWT signature validation during Okta Web Authentication. The vulnerability stems from the application not verifying that the JWT algorithm is configured for RSA, enabling an attacker to set the algorithm to "none" and craft forged tokens. This could allow an authenticated low-privilege user to impersonate any authorized user on the FTSP server, resulting in unauthorized access to system configuration and the ability to grant permissions to other systems protected by FTSP.
