freeradius: eap-pwd: authentication bypass via an invalid curve attack
FreeRADIUS before 3.0.19 mishandles the "each participant verifies that the received scalar is within a range, and that the received group element is a valid point on the curve being used" protection mechanism, aka a "Dragonblood" issue, a similar issue to CVE-2019-9498 and CVE-2019-9499.
A vulnerability was found in FreeRadius. An invalid curve attack allows an attacker to authenticate as any user, without knowing the password. FreeRADIUS doesn't verify whether the received elliptic curve point is valid. The highest threat from this vulnerability is to data confidentiality and integrity.

# 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-2019-11235 [CRITICAL] CVE-2019-11235 freeradius: eap-pwd: authentication bypass via an invalid curve attack
CVE-2019-11235 freeradius: eap-pwd: authentication bypass via an invalid curve attack
A vulnerability was found in FreeRadius. An invalid curve attack allows an attacker to authenticate as any user (without knowing the password). The problem is that on the reception of an EAP-PWD Commit frame, FreeRADIUS doesn't verify whether the received elliptic curve point is valid.
