F5 Networks BIG-IP : TMM vulnerability (K10751325)

high Nessus Plugin ID 154678

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 11.6.5.3 / 12.1.6 / 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 K10751325 advisory.

- On versions 16.0.x before 16.0.1.1, 15.1.x before 15.1.3, 14.1.x before 14.1.4, 13.1.x before 13.1.4, 12.1.x before 12.1.6, and 11.6.x before 11.6.5.3, when the BIG-IP system is buffering packet fragments for reassembly, the Traffic Management Microkernel (TMM) may consume an excessive amount of resources, eventually leading to a restart and failover event. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. (CVE-2021-23011)

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 K10751325.
