F5 Networks BIG-IP : F5 ePVA vulnerability (K52340447)

high Nessus Plugin ID 170492

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 13.1.5 / 14.1.4.6 / 15.1.5.1 / 16.1.2.2 / 17.0.0. It is, therefore, affected by a vulnerability as referenced in the K52340447 advisory.

 - On F5 BIG-IP 16.1.x versions prior to 16.1.2.2, 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, and 13.1.x versions prior to 13.1.5, on platforms with an ePVA and the pva.fwdaccel BigDB variable enabled, undisclosed requests to a virtual server with a FastL4 profile that has ePVA acceleration enabled can cause the Traffic Management Microkernel (TMM) process to terminate. Note:
 Software versions which have reached End of Technical Support (EoTS) are not evaluated (CVE-2022-28705)

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 K52340447.
