Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
