The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 24aa87c0-d452-11f1-bae2-3497f65b111b advisory.

    Oracle reports:
    The October 2026 Critical Patch Update contains 98 new security                 patches for Oracle MySQL, 29 of which may be remotely                 exploitable without authentication.
    The patches for MySQL Server 9.7 are contained in release 9.7.4.
                MySQL Shell is affected through the MySQL sources it bundles and                 links statically.
    Two further issues listed by Oracle, in the bundled curl and                 OpenSSL copies, do not apply to these ports: they build against                 the curl and OpenSSL of the system.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Optimizer).
    Supported versions that are affected are MySQL Server: 9.7.0-9.7.3; MySQL Cluster: 9.7.0-9.7.3. Easily     exploitable vulnerability allows low privileged attacker with network access via multiple protocols to     compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in     unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server, MySQL     Cluster. (CVE-2026-101620)

Note that Nessus relies on the presence of the package as reported by the vendor.

The versions of MySQL Server installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Compiling (OpenSSL)).
    Supported versions that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster:
    8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows unauthenticated     attacker with network access via multiple protocols to compromise MySQL Server, MySQL Cluster. Successful attacks of     this vulnerability can result in takeover of MySQL Server, MySQL Cluster. (CVE-2025-15467)

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: Group Replication GCS).
    Supported versions that are affected are MySQL Server: 8.4.0-8.4.12, 9.7.0-9.7.3, 26.7.0-26.7.1; MySQL Cluster:
    8.0.0-8.0.49, 8.4.0-8.4.12, 9.7.0-9.7.3 and 26.7.0-26.7.1. Easily exploitable vulnerability allows unauthenticated     attacker with access to the physical communication segment attached to the hardware where the MySQL Server, MySQL     Cluster executes to compromise MySQL Server, MySQL Cluster. Successful attacks of this vulnerability can result in     takeover of MySQL Server, MySQL Cluster. (CVE-2026-101781)

  - Vulnerability in the MySQL Server, MySQL Cluster product of Oracle MySQL (component: Server: JSON).
