CVE-2023-45249Acronis Cyber Infrastructure — shipped default passwords

Acronis Cyber Infrastructure ships with default passwords, so anyone who can reach the service runs commands on it without logging in first. Builds before 5.0.1-61, 5.1.1-71, 5.2.1-69, 5.3.1-53 and 5.4.4-132 are affected.

YOUR NEXT MOVE

Update to a build named in the Acronis advisory, then change every account still carrying its shipped password — starting with the ones reachable from the network.
