CVE-2023-52160 Auth bypass in n/a

What is CVE-2023-52160?

CVE-2023-52160 is a medium-severity authentication bypass vulnerability in Debian Debian Linux, published on 22 Feb 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

Official description

The implementation of PEAP in wpa_supplicant through 2.10 allows authentication bypass. For a successful attack, wpa_supplicant must be configured to not verify the network's TLS certificate during Phase 1 authentication, and an eap_peap_decrypt vulnerability can then be abused to skip Phase 2 authentication. The attack vector is sending an EAP-TLV Success packet instead of starting Phase 2. This allows an adversary to impersonate Enterprise Wi-Fi networks.

Weakness: CWE-287
