The server implementation of the EAP-MSCHAPv2 protocol in the eap-mschapv2 plugin in strongSwan 4.2.12 through 5.x before 5.3.4 does not properly validate local state, which allows remote attackers to bypass authentication via an empty Success message in response to an initial Challenge message. La implementación del servidor del protocolo EAP-MSCHAPv2 en el plugin eap-mschapv2 en strongSwan 4.2.12 hasta la versión 5.x en versiones anteriores a 5.3.4 no valida adecuadamente el estado local, lo que permite a atacantes remotos eludir la autenticación a través de un mensaje Success vacío en respuesta a un mensaje Challenge inicial. • http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00025.html http://lists.opensuse.org/opensuse-updates/2015-11/msg00139.html http://www.debian.org/security/2015/dsa-3398 http://www.securityfocus.com/bid/84947 http://www.ubuntu.com/usn/USN-2811-1 https://www.strongswan.org/blog/2015/11/16/strongswan-vulnerability-%28cve-2015-8023%29.html • CWE-20: Improper Input Validation CWE-264: Permissions, Privileges, and Access Controls •

strongSwan 4.3.0 through 5.x before 5.3.2 and strongSwan VPN Client before 1.4.6, when using EAP or pre-shared keys for authenticating an IKEv2 connection, does not enforce server authentication restrictions until the entire authentication process is complete, which allows remote servers to obtain credentials by using a valid certificate and then reading the responses. strongSwan 4.3.0 hasta 5.x anterior a 5.3.2 y strongSwan VPN Client anterior a 1.4.6, cuando utiliza claves EAP o precompartidas para la autenticación de una conexión IKEv2, no refuerza las restricciones de autenticación de servidores hasta que el proceso de autenticación entero se haya completado, lo que permite a servidores remotos obtener credenciales mediante el uso de un certificado válido y posteriormente la lectura de las respuestas. • http://lists.opensuse.org/opensuse-updates/2015-06/msg00040.html http://www.debian.org/security/2015/dsa-3282 http://www.openwall.com/lists/oss-security/2015/05/29/6 http://www.openwall.com/lists/oss-security/2015/05/29/7 http://www.openwall.com/lists/oss-security/2015/06/08/4 http://www.securityfocus.com/bid/74933 http://www.securitytracker.com/id/1032514 http://www.ubuntu.com/usn/USN-2628-1 https://bugzilla.suse.com/show_bug.cgi?id=933591 https: • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

IKEv2 in strongSwan 4.0.7 before 5.1.3 allows remote attackers to bypass authentication by rekeying an IKE_SA during (1) initiation or (2) re-authentication, which triggers the IKE_SA state to be set to established. IKEv2 en strongSwan 4.0.7 anterior a 5.1.3 permite a atacantes remotos evadir autenticación mediante la recodificación de un IKE_SA durante (1) iniciación o (2) re-autenticación, lo que provoca el estado de IKE_SA sea configurado como establecido. • http://lists.opensuse.org/opensuse-security-announce/2014-04/msg00010.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00064.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00066.html http://secunia.com/advisories/57823 http://www.debian.org/security/2014/dsa-2903 http://www.securityfocus.com/bid/66815 http://www.strongswan.org/blog/2014/04/14/strongswan-authentication-bypass-vulnerability-%28cve-2014-2338%29.html • CWE-287: Improper Authentication •
