Unauthenticated firewall interruption via forged-traffic flood
Published Aug 24, 2022 · Updated Aug 3, 2024
Denial of service in affected Stormshield Network Security releases allows remote attackers to interrupt firewall service via forged traffic. The firewall exhausts processing capacity when flooded with specific forged traffic, but Stormshield has not disclosed the affected packet path or parsing operation. No authentication or user interaction is required; sustained traffic can make the firewall unavailable, without reported confidentiality or integrity impact.
