Attackers can exploit this flaw to read sensitive files such as /etc/passwd or configuration and credential files, and the same endpoint's support for http(s) URLs also enables server-side request forgery against internal network resources. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-17.","state":0,"publishedAt":"2026-10-02T18:38:24.013+00:00","modifiedAt":"2026-10-02T20:14:15.156+00:00","affected":[{"ecosystem":"Vendor product","name":"e-Bridge","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"Weaver\",\n                    \"product\": \"e-Bridge\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"*\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5,"severity":"HIGH"}],"references":["https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/weaver/weaver-ebridge-lfi.yaml","https://www.weaver.com.cn/cs/ebridge_full_log_en.html","https://www.vulncheck.com/advisories/weaver-e-bridge-unauthenticated-arbitrary-file-read-via-saveyzjfile"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2020-37278","license":"CVE Program Terms of Use","key":"cve-program:CVE-2020-37278","identifiers":["CVE-2020-37278"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
