Slackware Linux 15.0 / current wpa_supplicant Vulnerability (SSA:2024-059-01)

medium Nessus Plugin ID 191121

Language:

Synopsis

The remote Slackware Linux host is missing a security update to wpa_supplicant.

Description

The version of wpa_supplicant installed on the remote host is prior to 2.10. It is, therefore, affected by a vulnerability as referenced in the SSA:2024-059-01 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

Upgrade the affected wpa_supplicant package.
