CVE-2023-52160
- Severity: medium (CVSS 6.5 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 1.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2024-02-22 · updated 2026-06-17
- Weakness: CWE-287
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.
Affected products
- Debian Linux: 10.0
- Fedoraproject Fedora: 38, 39
- Red Hat Enterprise Linux: 8.0, 9.0
- Canonical Ltd. wpa_supplicant: through 2.10
