Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions that are affected are 8.0.0-8.0.25. Easily exploitable vulnerability allows low 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. CVSS 3.1 Base Score 6.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

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 product of Oracle MySQL (component: Server: DML). Supported versions     that are affected are 8.0.0-8.0.25. Easily exploitable vulnerability allows low 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-2025-50076)

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

The version of mysql 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-2025-50076 advisory.

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions     that are affected are 8.0.0-8.0.25. Easily exploitable vulnerability allows low 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-2025-50076)

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

The version of MySQL running on the remote host is 8.0.x prior to 8.0.26. It is, therefore, affected by multiple vulnerabilities, including the following, as noted in the July 2021 Critical Patch Update advisory:

  - curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being   used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate   circumstances to potentially reach remote code execution in the client. (CVE-2021-22901)

  - LZ4 before 1.9.2 has a heap-based buffer overflow in LZ4_write32 (related to LZ4_compress_destSize), affecting   applications that call LZ4_compress_fast with a large input. (This issue can also lead to data corruption.)   (CVE-2019-17543)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are affected   are 5.7.34 and prior and 8.0.25 and prior. Difficult to exploit 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-2021-2372)

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