How to fix?

Upgrade Debian:10 isakmpd to version 20041012-4 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream isakmpd package and not the isakmpd package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

isakmpd in OpenBSD 3.8, 3.9, and possibly earlier versions, creates Security Associations (SA) with a replay window of size 0 when isakmpd acts as a responder during SA negotiation, which allows remote attackers to replay IPSec packets and bypass the replay protection.
