FreeBSD : strongswan - Incorrect Handling of Early EAP-Success Messages (ccaea96b-7dcd-11ec-93df-00224d821998)

critical Nessus Plugin ID 157235

Language:

Synopsis

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

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ccaea96b-7dcd-11ec-93df-00224d821998 advisory.

 - In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication. (CVE-2021-45079)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
