Security Advisory Description
When the BIG-IP 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 environments, this limits the attack surface to other
endpoints under the same administration. (CVE-2017-6156)
Impact
A remote attacker may be able to disrupt or impersonate the tunnels that have
completed phase 1 IPsec negotiations.
