F5 Networks BIG-IP : BIG-IP IPsec tunnel endpoint vulnerability (K05263202)

medium Nessus Plugin ID 118623

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 11.5.6 / 11.6.1 HF2 / 12.1.2 / 13.0.0. It is, therefore, affected by a vulnerability as referenced in the K05263202 advisory.

- When the F5 BIG-IP 12.1.0-12.1.1, 11.6.0-11.6.1, 11.5.1-11.5.5, or 11.2.1 system is configured with a wildcard IPSec tunnel endpoint, it may allow a remote attacker to disrupt or impersonate the tunnels that have completed phase 1 IPSec negotiations. The attacker must possess the necessary credentials to negotiate the phase 1 of the IPSec exchange to exploit this vulnerability; in many environment this limits the attack surface to other endpoints under the same administration. (CVE-2017-6156)

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 K05263202.
