Nuuo Central Management Server User Session Token Bruteforce
Nuuo Central Management Server below version 2.4 has a flaw where it sends the heap address of the user object instead of a real session number when a user logs in. This can be used to reduce the keyspace for the session number from 10 million to 1.2 million, and with a bit of analysis it can be guessed in less than 500k tries. This module does exactly that - it uses a computed occurence table to try the most common combinations up to 1.2 million to try to guess a valid user session. This session number can then be used to achieve code execution or download files - see the other Nuuo CMS auxiliary and exploit modules. Note that for this to work a user has to be logged into the system.
