Technical DetailsThe flaw exists but it is not exploitable
Technical Details Explanation



By sending large passwords, a remote user can enumerate users on system that runs SSHD. This problem exists in most modern configuration due to the fact that it takes much longer to calculate SHA256/SHA512 hash than BLOWFISH hash.
A timing attack on SSH authentications.  Which through trial and error and enumerate users allowed to login via SSH to a system.


The flaw exists but does not add an additional security risk.
Enumerating users is not useful as Authentication Manager only has a single user who can login; i. e., the appliance administrator (rsaadmin), and this username is included in the publicly available documentation.
