The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be used for full password recovery.
Affected configurations
| CPE | Name | Operator | Version |
|---|---|---|---|
| w1.fi:hostapd | w1.fi hostapd | le | 2.8 |
