# Vulnerability Summary
## First Disclosure
Summarized, the Dragonfly handshake of WPA3 and EAP-pwd is supposed to prevent dictionary attacks. However, we discovered design flaws that still enable an adversary to perform dictionary attacks. In particular, we discovered the following design flaws in WPA3 and EAP-pwd:
- Against EAP-pwd, a timing leak exists for all supported elliptic curves. An adversary within range of the victim can induce clients to connect to the adversary's Access Point (AP) and exploit this timing leak. The leaked information can be use

CVE-2019-11234 [CRITICAL] CVE-2019-11234 freeradius: eap-pwd: fake authentication using reflection
CVE-2019-11234 freeradius: eap-pwd: fake authentication using reflection
A vulnerability was found in FreeRadius. An attacker can reflect the received scalar and element from the server in it's own commit message, and subsequently reflect the confirm value as well. This causes the adversary to successfully authenticate as the victim. Fortunately, the adversary will not posses the negotiated session key, meaning the adversary cannot actually perform any actions as this user.
