Score breakdown

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.

Notes


mdeslaur

Commit listed in this CVE is only a workaround for certain unrelated scenarios, as upstream claims the real issue here is misconfiguration and external components that generate bad configurations that don't follow the documentation. See the following: http://lists.infradead.org/pipermail/hostap/2024-February/042362.html http://lists.infradead.org/pipermail/hostap/2024-February/042364.html Marking wpa in this CVE as deferred as there is no fix available. Front-end components that generate bad configuration files should be added to this CVE if any are discovered.
