CVE-2019-13456

In FreeRADIUS 3.0 through 3.0.19, 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. This information leakage is...

CVE-2019-13456

CVE-2019-13456 concerns FreeRADIUS 3.0–3.0.19, where, on average, 1 in 2048 EAP-pwd handshakes leaks information. Specifically, the password element can not be found within 10 iterations of the hunting-and-pecking loop, enabling an information leak that leaks enough to recover a user’s password. ...

Internet Bug Bounty: Dragonblood: Design and Implementation Flaws in WPA3 and EAP-pwd

Full background information is at our website and detailed information can be found in our research paper. 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 enabl...

Ubuntu 18.04 LTS : wpa_supplicant and hostapd vulnerability (USN-4098-1)

The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4098-1 advisory. It was discovered that wpasupplicant and hostapd were vulnerable to a side channel attack against EAP- pwd. A remote attacker could possibly use this issue to...

Design/Logic Flaw

The implementations of SAE and EAP-pwd in hostapd and wpasupplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel...

CVE-2019-13377

CVE-2019-13377 affects the SAE and EAP-pwd implementations in hostapd and wpa_supplicant (2.x up to 2.8). The root cause is a side-channel weakness: observable timing differences and cache access patterns when Brainpool curves are used, enabling an attacker to recover parts of the password and po...
