The version of MySQL running on the remote host is 5.7.x prior to 5.7.30. It is, therefore, affected by multiple vulnerabilities, as noted in the April 2020 Critical Patch Update advisory:
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Parser). 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 takeover of MySQL Server. (CVE-2021-2144)
Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are affected are 5.6.47 and prior, 5.7.29 and prior and 8.0.18 and prior. This difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client. Successful attacks of this vulnerability can result in unauthorized read access to a subset of MySQL Client accessible data. (CVE-2020-2922)
Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). 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 as well as unauthorized update, insert or delete access to some of MySQL Server accessible data. (CVE-2020-2760)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
