"The version of mysql-connector-java installed on the remote host is prior to 5.1.25-3. It is, therefore, affected by a
vulnerability as referenced in the ALAS2-2023-2017 advisory.

  - Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/J). Supported versions
    that are affected are 8.0.19 and prior and 5.1.48 and prior. Difficult to exploit vulnerability allows
    unauthenticated attacker with network access via multiple protocols to compromise MySQL Connectors.
    Successful attacks require human interaction from a person other than the attacker. Successful attacks of
    this vulnerability can result in unauthorized update, insert or delete access to some of MySQL Connectors
    accessible data as well as unauthorized read access to a subset of MySQL Connectors accessible data and
    unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Connectors.
    (CVE-2020-2934)

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