high Nessus Plugin ID 154697

Language:

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 13.1.4 / 14.1.4 / 15.1.3 / 16.0.1.1 / 16.1.0.
It is, therefore, affected by a vulnerability as referenced in the K04234247 advisory.

 - On BIG-IP versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.3, 14.1.x before 14.1.4, and 13.1.x before 13.1.4, lack of input validation for items used in the system support functionality may allow users granted either Resource Administrator or Administrator roles to execute arbitrary bash commands on BIG-IP. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
 (CVE-2021-23012)

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