This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.\n\nIf the Firebox was previously configured with the mobile user VPN with IKEv2 or a branch office VPN using IKEv2 to a dynamic gateway peer, and both of those configurations have since been deleted, that Firebox may still be vulnerable if a branch office VPN to a static gateway peer is still configured.","published":"2025-12-19T01:16:06.000Z","lastModified":"2026-09-09T04:17:53.000Z","status":"Analyzed","sourceIdentifier":"5d1c2695-1a31-4499-88ae-e847036fd7e3","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-787"],"affected":["watchguard/fireware"],"epss":{"score":0.29423,"percentile":0.98178,"date":"2026-10-30","history":[{"date":"2026-10-25","score":0.29423,"percentile":0.98167}]},"kev":{"listed":true,"dateAdded":"2025-12-19","dueDate":"2025-12-26","knownRansomwareCampaignUse":"Known","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nCheck for signs of potential compromise on all internet accessible instances after applying mitigations.
