{"id":"CVE-2025-71284","summary":"Synway SMG Gateway Management Software OS Command Injection via radius_address","details":"Synway SMG Gateway Management Software contains an OS command injection vulnerability in the RADIUS configuration endpoint at /en/9-2radius.php where the radius_address POST parameter is split and interpolated directly into a sed command without sanitization. An unauthenticated remote attacker can inject arbitrary shell commands by submitting a POST request with crafted radius_address, radius_address2, shared_secret2, source_ip, timeout, or retry parameters along with save=1 and enable_radius=1 to achieve remote code execution. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-07-11 (UTC).","modified":"2026-10-09T02:30:51.997192405Z","published":"2026-04-30T16:08:17.336Z","database_specific":{"cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71284.json","cna_assigner":"VulnCheck"},"references":[{"type":"WEB","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/synway/synwaysmg-radius-rce.yaml"},{"type":"WEB","url":"https://www.synway.net/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/71xxx/CVE-2025-71284.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-71284"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/synway-smg-gateway-management-software-os-command-injection-via-radius-address"},{"type":"EVIDENCE","url":"https://mp.weixin.qq.com/s/PyepoFSuQ63E3RnpQa9nsA"},{"type":"EVIDENCE","url":"https://mrxn.net/jswz/synway-9-2radius-rce.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/projectdiscovery/nuclei-templates","events":[{"introduced":"0"},{"last_affected":"0"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"0"}]}}],"versions":["0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-71284.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
