"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 K16162257 advisory.

    Improper input validation in the BIOS firmware for some Intel(R) Processors may allow a privileged user to
    potentially enable an escalation of privilege via local access.(CVE-2021-0154)ImpactA local attacker
    logged in as a privileged user can exploit the vulnerability to gain access to restricted information on
    an affected system.The following F5 hardware platforms are vulnerable to CVE-2021-0154:BIG-IP i850BIG-IP
    i2000 seriesBIG-IP i4000 seriesBIG-IP i5000 seriesBIG-IP i7000 seriesBIG-IP i10000 seriesBIG-IP i11000
    seriesBIG-IP i15000 seriesVIPRION B4450NFor more information, refer toK9476: The F5 hardware/software
    compatibility matrix.All versions of Virtual Edition (VE) for the BIG-IP and BIG-IQ products are
    potentially impacted if the processors underlying the VE installations areaffected. Microcode updates
    from Intel are available to address this issue but must be applied at the hardware level, which is outside
    the scope of the ability of F5 to support or patch.

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.");
