This could result in the blocking of almost all network traffic, making the firewall unreachable. An attacker could exploit this via forged and properly timed traffic to cause a denial of service.","published":"2022-03-15T21:15:10.000Z","lastModified":"2026-06-17T04:31:06.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":[],"affected":["stormshield/stormshield network security"],"epss":{"score":0.0093,"percentile":0.60342,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.93%).
