"The version of F5 Networks BIG-IP installed on the remote host is prior to 17.1.3 / 17.5.1.1. It is, therefore, affected
by a vulnerability as referenced in the K000150010 advisory.

    After a reboot, the BIG-IP AFMipsdprocess may unexpectedly fail to enforce the Intrusion Prevention System
    (IPS) signatures configured for protocol inspection profiles. This condition can persist for some time
    even though the system reports the protocol inspection profiles asREADY.This issue occurs when all of the
    following conditions are met:The user configured a significant number of protocol inspection profiles,
    each with one or more services enabled.The user assigned these protocol inspection profiles to one or more
    virtual servers and saved the configuration.The BIG-IP AFM system was subsequently rebooted, including
    manual or unexpected reboots.

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
number.");
