high Nessus Plugin ID 124219

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not to validate the received scalar and element values in EAP-pwd-Commit messages properly. This could result in attacks that would be able to complete EAP-pwd authentication exchange without the attacker having to know the used password.

See https://w1.fi/security/2019-4/eap-pwd-missing-commit-validation.txt for a detailed description of the bug. Impact : All wpa_supplicant and hostapd versions with EAP-pwd support.

Solution

Update the affected packages.
