Am I affected?

Description

In SapphireIMS 5.0, it is possible to take over an account by sending a request to the Save_Password form as shown in POC. Notice that we do not require a JSESSIONID in this request and can reset any user’s password by changing the username to that user and password to base64(desired password).
