In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.1.3, 12.1.0-12.1.3.7, 11.6.1-11.6.3.2, or 11.5.1-11.5.8, when remote authentication is enabled for administrative users and all external users are granted the "guest" role, unsanitized values can be reflected to the client via the login page. This can lead to a cross-site scripting attack against unauthenticated clients.

On F5 BIG-IP 12.1.0-12.1.3.1, 11.6.1-11.6.3.1, 11.5.1-11.5.5, or 11.2.1, carefully crafted URLs can be used to reflect arbitrary content into GeoIP lookup responses, potentially exposing clients to XSS.

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.
