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-2025-53118 and the vendor advisory. Establish affected and fixed versions, including vendor backports. The record lists: Securden Unified PAM: affected 9.0.* through 11.3.1. Cite sources and retrieval dates; flag anything you cannot verify.\n2. Inventory deployments of Securden Unified PAM: 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: F5: rule exists, check whether it is enabled. Live data: https://cve.vigilbase.com/api/v1/cves/CVE-2025-53118. 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. Keep a WAF rule in place while you patch: F5 ships a rule you may need to switch on. A WAF rule reduces exposure; it does not replace the patch.\nMore: https://cve.vigilbase.com/cve/CVE-2025-53118"},"measured":[{"engineId":"owasp-crs","engineName":"OWASP Core Rule Set","engineVersion":"4.25.0","runtime":"Coraza v3.8.1","config":"paranoia level 1, anomaly threshold 5, default CRS settings","ranAt":"2026-11-02T13:02:57.000Z","verdict":"passed","templateId":"CVE-2025-53118","templatePath":"http/cves/2025/CVE-2025-53118.yaml","requests":3,"blockedRequests":0,"rules":[],"note":"","requestDetail":[{"method":"GET","path":"/thirdparty-access","status":200,"blocked":false,"rules":[]},{"method":"GET","path":"/get_csrf_token","status":200,"blocked":false,"rules":[]},{"method":"GET","path":"/get_date_picker_format","status":200,"blocked":false,"rules":[]}]},{"engineId":"owasp-crs","engineName":"OWASP Core Rule Set","engineVersion":"4.25.0","runtime":"Coraza v3.8.1","config":"paranoia level 2, anomaly threshold 5, default CRS settings","ranAt":"2026-11-02T13:03:28.000Z","verdict":"passed","templateId":"CVE-2025-53118","templatePath":"http/cves/2025/CVE-2025-53118.yaml","requests":3,"blockedRequests":0,"rules":[],"note":"","requestDetail":[{"method":"GET","path":"/thirdparty-access","status":200,"blocked":false,"rules":[]},{"method":"GET","path":"/get_csrf_token","status":200,"blocked":false,"rules":[]},{"method":"GET","path":"/get_date_picker_format","status":200,"blocked":false,"rules":[]}]}],"sightings":{"honeypot":{"days":2,"first":"2026-10-15","last":"2026-10-29"},"catalog":null,"reports":[],"telegram":null,"days":{"honeypot":["2026-10-15","2026-10-29"],"reports":[],"telegram":[]}},"social":{"total":0,"first_seen":null,"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":0}],"top_posts":[],"exploit_repositories":[]}}
