Summary

This vulnerability affects F5 BIG-IP systems when configured with wildcard IPSec tunnel endpoints. A remote attacker, armed with valid credentials, can disrupt or impersonate established tunnels that have completed phase 1 IPSec negotiations. This situation is particularly concerning as it limits the attack surface to endpoints managed within the same administrative domain, potentially exposing sensitive data and compromising network integrity.
