The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An attacker may be able to use invalid scalar/element values to complete authentication, gaining session key and network access without needing or learning the password. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.

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-2019-9498 [HIGH] CVE-2019-9498 wpa_supplicant: EAP-pwd server missing commit validation for scalar/element
CVE-2019-9498 wpa_supplicant: EAP-pwd server missing commit validation for scalar/element
An attack using invalid scalar/element values is possible against the EAP-pwd server since hostapd and wpa_supplicant did not validate these values in the received EAP-pwd-Commit messages. When processing an EAP-pwd Commit frame, the peer's scalar and element (elliptic curve point) were not validated. This allowed an adversary to bypass authentication, and impersonate any user if the crypto implementation did not verify the validity of the EC point.
The vulnerability is only exploitable if OpenSSL version 1.0.2 or lower is used, or if LibreSSL or wolfssl is used. Newer versions of OpenSSL (and also BoringSSL) implicitly validate the elliptic curve point in EC_POINT_set_affine_coordinates_GFp(), prev

One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
## Abstract
Currently, the development of IoT firmware heavily depends on third-party components (TPCs) to improve development efficiency. Nevertheless, TPCs are not secure, and the vulnerabilities in TPCs will influence the security of IoT firmware. Existing works pay less attention to the vulnerabilities caused by TPCs, and we still lack a comprehensive understanding of the security impact of TPC vulnerability against firmware. To fill in the knowledge gap, we design and implement , which leverages syntactical features and control-flow graph features to detect the TPCs in firmware, and then recognizes the corresponding vulnerabilities. Based on , we present the first l
