Like Heartbleed, new flaw worries researchers about open-source collaboration.

On the heels of the discovery of the Heartbleed bug, arguably the biggest security story of the year so far, OpenSSL has disclosed another serious vulnerability – one that could lead to man-in-the-middle attacks.

Meanwhile, the Cupid prototype exploit has surfaced that can use the Heartbleed vulnerability in a new way, over wireless networks, indicating that OpenSSL concerns are far from resolved.

“A man-in-the-middle attack is like a phone tap; someone breaks into the line you’re using to communicate and is able to get all the information going back and forth,” explained Jonathan Sander, strategy and research officer for STEALTH bits Technologies, in a comment to Infosecurity. “The encryption OpenSSL is supposed to grant you is meant to protect you from that, but when the encryption is broken, the protection is gone.”

Like Heartbleed, the flaw has to do with the implementation of cryptography methods within OpenSSL. Unlike Heartbleed though, the new flaw will likely have a limited scope because the attack can only be performed if the perpetrator has access to both a vulnerable client and a vulnerable server.
