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.


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:

Marking wpa in this CVE as deferred as there is no fix

Front-end components that generate bad configuration files
should be added to this CVE if any are discovered.
