Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

Brocade ASCG before 3.5.0 improperly processes user input by evaluating form data prior to validation. When an authenticated user submits a configuration form, the submitted text could immediately be processed. A malicious actor with basic access can supply crafted input to execute arbitrary code on the server and take control of the application.
