This vulnerability affects both the mobile user VPN with IKEv2 and the branch office VPN using IKEv2 when configured with a dynamic gateway peer.\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":"2025-09-17T07:29:23.738Z","modified":"2026-08-10T15:28:40.461Z","cvss":null,"epss":{"score":0.913,"percentile":0.99804,"asOf":"2026-08-28"},"cisaKev":{"dateAdded":"2025-11-12","dueDate":"2025-12-03","knownRansomwareCampaignUse":false},"exploitsKnown":1,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://psirt.watchguard.com/CVE-2025-9242"},{"type":"ADVISORY","url":"https://www.watchguard.com/wgrd-psirt/advisory/wgsa-2025-00015"},{"type":"EXPLOIT","url":"https://github.com/watchtowrlabs/watchTowr-vs-WatchGuard-CVE-2025-9242/blob/main/watchTowr-vs-WatchGuard-CVE-2025-9242.py"},{"type":"WEB","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2025-9242"}],"provenance":{"sources":["OSV.dev","NVD","CISA KEV","FIRST.org (EPSS)"],"lastVerified":"2026-08-10T15:28:40.461Z"}}
