Heartbleed Bug Exploited Over Extensible Authentication Protocol 44

wiredmikey (1824622) writes "While most organizations have patched the Heartbleed bug in their OpenSSL installations, a security expert has uncovered new vectors for exploiting the vulnerability, which can impact enterprise wireless networks, Android devices, and other connected devices. Dubbed 'Cupid,' the new attack method was recently presented by Portuguese security researcher Luis Grangeia, who debunked theories that Heartbleed could only be exploited over TCP connections, and after the TLS handshake. 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."

    Which is why my next phone won't be Android. I'm not sure what OS it's going to be running, but Android seems to be the worst at getting updates. Many phones don't even get a single update after they are shipped. Also, the updates from many phones are carrier specific because they had carrier specific firmware when they were originally sold, So there might be an update for your phone, but you can't easily install it because it's not for your carrier. If you go with a smaller carrier, you are often out of luck. After being burned by this type of situation with Android on my first real smart phone, I will not go with Android again.

No man is an island if he's on at least one mailing list.
