The version of MySQL running on the remote host is 5.7.29 and prior or 8.0.19 and prior. It is, therefore, affected by a vulnerability, as noted in the July 2020 Critical Patch Update advisory:
A Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Replication). Supported versions that are affected are 5.7.29 and prior and 8.0.19 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
