GEN005539 - The SSH daemon must not allow compression or must only allow compression after successful authentication.

Information

If compression is allowed in an SSH connection prior to authentication, vulnerabilities in the compression software could result in compromise of the system from an unauthenticated connection, potentially with root privileges.

Solution

Edit the SSH daemon configuration and add or edit the Compression setting value to no or delayed.
