Due to insufficient validation of its local state the server implementation of the EAP-MSCHAPv2 protocol in the eap-mschapv2 plugin can be tricked into successfully concluding the authentication without providing valid credentials. It's possible to recognize such attacks by looking at the server logs. The following log message would be seen during the client authentication: EAP method EAP_MSCHAPV2 succeeded, no MSK established For the oldstable distribution (wheezy), this problem has been fixed in version 4.5.2-1.5+deb7u8. For the stable distribution (jessie), this problem has been fixed in version 5.2.1-6+deb8u2. For the testing distribution (stretch), this problem has been fixed in version 5.3.3-3. For the unstable distribution (sid), this problem has been fixed in version 5.3.3-3. We recommend that you upgrade your strongswan packages.
