Perform a read-only assessment within your authorized access. Do not send exploit traffic, scan third-party systems, change configuration or restart services.\n\n1. Verify the CVE record at https://www.cve.org/CVERecord?id=CVE-2026-114425 and the vendor advisory. Establish affected and fixed versions, including vendor backports. The record lists: SEPPmail AG SEPPmail Secure Email Gateway (SEG): affected before 15.1.1. Cite sources and retrieval dates; flag anything you cannot verify.\n2. Inventory deployments of SEPPmail Secure Email Gateway (SEG): asset, environment, owner where known, installed version or build, and how you confirmed it (package metadata, a version endpoint, image tags). An image tag alone does not prove the running version.\n3. Identify which deployments are reachable from the internet or untrusted networks, and through which paths (direct origin, load balancer, CDN or WAF).\n4. Assess compensating controls separately from patch status. Current edge WAF coverage for this CVE: no edge WAF vendor names it. Live data: https://cve.vigilbase.com/api/v1/cves/CVE-2026-114425. Check whether the rule is enabled and in block mode on each path, and whether any path bypasses the WAF. A WAF rule is not a patch.\n5. Check logs on exposed instances for requests matching the public exploit, if your access allows.\n\nReturn a short summary and a table: asset | version/build | assessment (affected, fixed, not applicable, unknown) | exposure | compensating control | evidence | next action. List what you could not assess and the access needed to resolve it. Do not infer absence of compromise from patch status or a lack of alerts.\n\nRemediation guidance: Apply the vendor's fix; the advisory lists the affected and fixed versions. Do not rely on WAF defaults: no edge vendor names this CVE. Restrict access to the vulnerable component or add a custom rule until it is patched.\nMore: https://cve.vigilbase.com/cve/CVE-2026-114425"},"measured":[],"sightings":null,"social":{"total":5,"first_seen":"2026-11-04T08:46:23.000Z","daily":[{"day":"2026-10-22","posts":0},{"day":"2026-10-23","posts":0},{"day":"2026-10-24","posts":0},{"day":"2026-10-25","posts":0},{"day":"2026-10-26","posts":0},{"day":"2026-10-27","posts":0},{"day":"2026-10-28","posts":0},{"day":"2026-10-29","posts":0},{"day":"2026-10-30","posts":0},{"day":"2026-10-31","posts":0},{"day":"2026-11-01","posts":0},{"day":"2026-11-02","posts":0},{"day":"2026-11-03","posts":0},{"day":"2026-11-04","posts":5}],"top_posts":[{"source":"x","kind":"post","url":"https://x.com/EnclaveRadar/status/2117914918926110825","author":"EnclaveRadar","author_name":"Enclave Radar","avatar_url":"https://pbs.twimg.com/profile_images/2116963272138121217/F3O3nWOo_bigger.jpg","text":"🆕 New CVE: CVE-2026-114425 (CVSS 9.2)\nSEPPmail Secure Email Gateway (SEG) · Information disclosure\nRemote, no login needed.\n\nSEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment…\n\nhttps://t.co/cDf7EoPaOZ","engagement":0,"posted_at":"2026-11-04T09:40:40.000Z"},{"source":"bluesky","kind":"post","url":"https://bsky.app/profile/stackflag.bsky.social/post/3mzi2oz2zbr2t","author":"stackflag.bsky.social","author_name":"STACKFLAG","avatar_url":"https://cdn.bsky.app/img/avatar/plain/did:plc:zhe53h7ajlloep2oso5pqxzj/bafkreigtuhh5jkztpd2jbpwmsgwljrln6miskcl62es3xsgiziejo5gdve","text":"CVE-2026-114425 - seppmail secure email gateway (seg)\nThe SEPPmail Secure Email Gateway can be tricked by a specially crafted large file transfer attachment to read, move, or delete files on the server.
