medium Nessus Plugin ID 154677

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 13.1.3.6 / 14.1.4 / 15.1.2.1 / 16.0.1.1 / 16.1.0. It is, therefore, affected by a vulnerability as referenced in the K71891773 advisory.

 - When using BIG-IP APM 16.0.x before 16.0.1.1, 15.1.x before 15.1.2.1, 14.1.x before 14.1.4, 13.1.x before 13.1.3.6, or all 12.1.x and 11.6.x versions or Edge Client versions 7.2.1.x before 7.2.1.1, 7.1.9.x before 7.1.9.8, or 7.1.8.x before 7.1.8.5, the session ID is visible in the arguments of the f5vpn.exe command when VPN is launched from the browser on a Windows system. Addressing this issue requires both the client and server fixes. Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. (CVE-2021-23002)

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