critical Nessus Plugin ID 138234

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 16.0.0. It is, therefore, affected by a vulnerability as referenced in the K72540690 advisory.

 The default deployment mode for BIG-IP high availability (HA) pair mirroring is insecure. This is a control plane issue that is exposed only on the network used for mirroring.(CVE-2020-5884)ImpactOn-path attackers may be able to read and modify data in transit. Depending on the deployment, this may include state mirroring messages, client connection details, client data packets, and/or client persistence data.
 Only high availability (HA) pairs with session mirroring or connection mirroring enabled are vulnerable.

Tenable has extracted the preceding description block directly from the F5 Networks BIG-IP security advisory.

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 K72540690.
