Synopsis
The remote Red Hat host is missing a security update for wpa_supplicant.Description
The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:2517 advisory.- 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. (CVE-2023-52160)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the RHEL wpa_supplicant package based on the guidance in RHSA-2024:2517.See Also
