Detailsinfo

A vulnerability was found in hostapd up to 2.10. It has been classified as problematic. Affected is an unknown code block of the component PKEX Code. CWE is classifying the issue as CWE-323. Nonces should be used for the present occasion and only once. The impact remains unknown. CVE summarizes:

In hostapd 2.10 and earlier, the PKEX code remains active even after a successful PKEX association. An attacker that successfully bootstrapped public keys with another entity using PKEX in the past, will be able to subvert a future bootstrapping by passively observing public keys, re-using the encrypting element Qi and subtracting it from the captured message M (X = M - Qi). This will result in the public ephemeral key X; the only element required to subvert the PKEX association.
