"The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by
a vulnerability as referenced in the K000141357 advisory.

    An issue was discovered in libxml2 before 2.11.7 and 2.12.x before 2.12.5. When using the XML Reader
    interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to
    an xmlValidatePopElement use-after-free.(CVE-2024-25062)

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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