Unlike the initial Heartbleed attack, which took place on TLS connections over TCP, the Cupid attack happens on TLS connections over the Extensible Authentication Protocol (EAP), an authentication framework typically used in wireless networks and peer-to-peer connections.
The researcher has confirmed that default installations of wpa_supplicant, hostapd, and freeradius (RADIUS server implementation) can be exploited on Ubuntu if a vulnerable version of OpenSSL is utilized. Mobile devices running Android 4.1.0 and 4.1.1 also use wpa_supplicant to connect to wireless networks, so they’re also affected.
Everything that uses OpenSSL for EAP TLS is susceptible to Cupid attacks. While he hasn’t been able to confirm it, the expert believes iPhones, iPads, OS X, other RADIUS servers besides freeradius, VoIP phones, printers, and various commercial managed wireless solutions could be affected.
