CVE-2020-23303:
Homebrew vulnerability analysis and mitigation
Overview
The implementations of SAE in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to side channel attacks as a result of cache access patterns. This vulnerability (CVE-2020-23303) exists because of an incomplete fix for CVE-2019-9494 (SUSE Linux).
Technical details
The vulnerability stems from cache access patterns that can be exploited through side-channel attacks in the SAE (Simultaneous Authentication of Equals) implementation. This affects both hostapd and wpa_supplicant components in versions prior to 2.10 (SUSE Linux).
Impact
The vulnerability could allow attackers to perform side-channel attacks to potentially extract sensitive information from the cache access patterns during SAE authentication processes (SUSE Linux).
Mitigation and workarounds
The issue has been fixed in hostapd and wpa_supplicant version 2.10. Users should upgrade to this version or later to address the vulnerability (SUSE Linux).
