We have one Cisco SG550X switch, I have just login using SSH protocol, After login the switch The switch got Restarted automatically below is OS Version of it. Is this Switch BUG, Due to this issue my LAN Network got down for 5 Minutes.
there is a security vulnerability alert out for SSH on the SG series switches. Basically, check if you have SSH user authentication by password enabled.
Notes: SSH is not enabled on the affected platforms by default. To verify if SSH is enabled, navigate to Security > TCP/UDP Services and look for the Enabled checkbox next to SSH Service. This issue is exploitable only with SSH User Authentication by Password enabled under Security > SSH Server > SSH User Authentication. (In 2.x software, this option is visible in Advanced display mode only.)
