What is CVE-2015-4171?

The strongSwan VPN Client and Server versions prior to 5.3.2 and 1.4.6 respectively, exhibit a significant vulnerability during the IKEv2 connection process. This flaw allows malicious remote servers to exploit EAP or pre-shared keys by bypassing server authentication controls until the entire authentication cycle has been finalized. As a result, an attacker can potentially extract sensitive credentials by using a legitimate certificate to obtain responses from the client or server, exposing users to unauthorized access and data breaches.
