"The version of mysql / mariadb installed on the remote CBL Mariner 2.0 host is prior to tested version. It is,
therefore, affected by a vulnerability as referenced in the CVE-2022-21427 advisory.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: FTS). Supported versions
    that are affected are 5.7.37 and prior and 8.0.28 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. (CVE-2022-21427)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
