Attackers can exploit improper bounds checking in password handling to overflow a fixed-size buffer and achieve denial of service or remote code execution.","state":0,"publishedAt":"2026-04-03T21:22:40.634+00:00","modifiedAt":"2026-10-01T15:19:11.188+00:00","affected":[{"ecosystem":"Vendor product","name":"Hirschmann HiSecOS Classic Firewall (EAGLE, EAGLE One)","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Belden\",\n                    \"product\": \"Hirschmann HiSecOS Classic Firewall (EAGLE, EAGLE One)\",\n                    \"versions\": [\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"05.3.03\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\",\n                            \"lessThanOrEqual\": \"05.3.02\"\n                        }\n                    ],\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"},{"system":"CVSS 4.0","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","score":9.3,"severity":"CRITICAL"}],"references":["https://assets.belden.com/m/2d5657b3e5d721c6/original/Security-Bulletin-RADIUS-Authentication-BSECV-2018-04.pdf","https://www.vulncheck.com/advisories/hirschmann-hisecos-buffer-overflow-via-https-login"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2018-25237","license":"CVE Program Terms of Use","key":"cve-program:CVE-2018-25237","identifiers":["CVE-2018-25237"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
