1) Information disclosure (CVE-ID: CVE-2019-13456)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way FreeRadius processes EAP-pwd handshakes. on average 1 in every 2048 EAP-pwd handshakes fails because the password element cannot be found within 10 iterations of the hunting and pecking loop. This leaks information that an attacker can use to recover the password of any user.
