When an IKEv2 client authenticates the server with certificates and the client authenticates itself to the server using pre-shared key or EAP, the constraints on the server certificate are only enforced by the client after all authentication steps are completed successfully. A rogue server which can authenticate using a valid certificate issued by any CA trusted by the client could trick the user into continuing the authentication, revealing the username and password digest (for EAP) or even the cleartext password (if EAP-GTC is accepted).
For the oldstable distribution (wheezy), this problem has been fixed in version 4.5.2-1.5+deb7u7.
For the stable distribution (jessie), this problem has been fixed in version 5.2.1-6+deb8u1.
For the testing distribution (stretch), this problem has been fixed in version 5.3.1-1.
For the unstable distribution (sid), this problem has been fixed in version 5.3.1-1.
We recommend that you upgrade your strongswan packages.");
