Summary
The rate limit for entering a password to start a secure session was too low. This allowed for brute force password guessing when an attacker would gain access to an existing session of a user. We have solved the issue by making the password rate limit the same as the regular login procedure.
Bypassing the rate-limiting by setting Throttle value 0 to 5000 in Burp Suit tools Intruder's request engine option.
