Description

There must be a fixed length for user input parameters like “title” while adding SSH key. Allowing users to enter long strings may result in a DOS attack or memory corruption

Proof of Concept

1)Go to https://rdiffweb-demo.ikus-soft.com/prefs/sshkeys# endpoint .
2)Click on add SSH key.
3)Here you will see that there is no limit for the “title” while adding SSH key that allows a user to to set a very long string as long as 1 million characters .
4)This may possibly result in a memory corruption/DOS attack.

Mitigation: There must be a fixed length for the “title” while adding SSH key - upto 256 characters
