Dumb question: Our SolMan instances have no exposure to the internet. Does that lessen the severity of this exploit?
Solution Manager is not frequently exposed to the internet, limiting the overall impact. However, this limitation does not preclude a local attacker from exploiting this flaw.
Good point! Thank you...
