DESCRIPTION: Is my SonicWall vulnerable to CVE-2015-5600?
Are SonicWalls vulnerable to CVE-2015-5600?
No. This vulnerability affects configurations that have KbdInteractiveAuthentication set to yes. Default for KbdInteractiveAuthentication is to use whatever value ChallengeResponseAuthentication is set to, which is 'no' in default configurations in Debian.
SonicOS is built on vxWorks, which always enforces authentication through SonicOS shell login after SSH connection is established, so there is no way to bypass authentication.
