CVE-2016-1561
ExaGrid appliances with firmware before 4.8 P26 have a default SSH public key in the authorized_keys file for root, which allows remote attackers to obtain SSH access by leveraging knowledge of a private key from another installation or a firmware image.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 74.3%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
