Unauthenticated denial of service via SSLVPN connection flood
Published Mar 15, 2022 · Updated Aug 3, 2024
Denial of service in affected Stormshield Network Security releases allows remote attackers to block almost all firewall network traffic. The SSLVPN service processes a flood of forged, precisely timed connections until the loopback interface saturates. No authentication or user interaction is required, and saturation leaves the firewall unreachable by blocking almost all network traffic.
