{"schema":"threatline.record/2","record":{"id":"CVE-2020-37278","aliases":[],"summary":"Weaver e-Bridge Unauthenticated Arbitrary File Read via saveYZJFile","details":"Weaver e-Bridge contains an unauthenticated arbitrary file read vulnerability that allows remote attackers to access arbitrary files on the host system by supplying a file: URL to the downloadUrl parameter of the saveYZJFile endpoint. 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.","categories":["Unclassified"],"product":"e-Bridge","vendor":"Weaver","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2020-37278","source_modified_at":"2026-10-02T20:14:15.156Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"e-Bridge","vendor":"Weaver","versions":[{"status":"affected","version":"*","versionType":"custom"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00356,"percentile":0.28144,"score_date":"2026-10-23"},"published_at":"2026-10-02T18:38:24.013Z","modified_at":"2026-10-02T20:14:15.156Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2020-37278","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-02T20:14:15.156Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2020-37278","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/weaver/weaver-ebridge-lfi.yaml","tags":["technical-description"]},{"source":"CVE List","url":"https://www.weaver.com.cn/cs/ebridge_full_log_en.html","tags":["release-notes"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/weaver-e-bridge-unauthenticated-arbitrary-file-read-via-saveyzjfile","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-02T20:14:06.362998Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-02T20:14:15.156Z","content_hash":"70a7e0eadd0276cf080bfbc08087c911dbcdd31c09c6f97714d66084a51d8647"}}
