F5 Networks BIG-IP : Authenticated iControl REST in Appliance mode vulnerability (K11010341)

critical Nessus Plugin ID 163773

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 14.1.5 / 15.1.5.1 / 16.1.3 / 17.0.0. It is, therefore, affected by a vulnerability as referenced in the K11010341 advisory.

- In BIG-IP Versions 16.1.x before 16.1.3, 15.1.x before 15.1.5.1, 14.1.x before 14.1.5, and all versions of 13.1.x, when running in Appliance mode, an authenticated user assigned the Administrator role may be able to bypass Appliance mode restrictions, using an undisclosed iControl REST endpoint. A successful exploit can allow the attacker to cross a security boundary. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2022-35243)

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

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution K11010341.
