{"schema":"threatline.record/2","record":{"id":"CVE-2023-54405","aliases":[],"summary":"H3C CVM Unauthenticated File Upload via fileUpload/upload Token","details":"H3C CVM, the Cloud Virtualization Management component of the H3C CAS cloud platform, contains an unauthenticated arbitrary file upload vulnerability in the /cas/fileUpload/upload endpoint that allows remote attackers to write arbitrary files by manipulating the caller-supplied token parameter without restricting path traversal or file type. Attackers can exploit the path traversal in the token parameter to upload a malicious JSP file into a web-accessible directory and then request it to achieve remote code execution as the web-server user. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-14.","categories":["Network & edge"],"product":"CVM","vendor":"H3C","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2023-54405","source_modified_at":"2026-10-05T15:48:29.812Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"CVM","vendor":"H3C","versions":[{"status":"affected","version":"*","versionType":"custom"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":9.3,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.00588,"percentile":0.47428,"score_date":"2026-10-23"},"published_at":"2026-10-02T18:36:03.442Z","modified_at":"2026-10-05T15:48:29.812Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2023-54405","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T15:48:29.812Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2023-54405","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/other/h3c-cvm-arbitrary-file-upload.yaml","tags":["technical-description"]},{"source":"CVE List","url":"https://blog.csdn.net/qq_41904294/article/details/134697278","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://www.h3c.com/en/Support/Resource_Center/EN/Cloud_Computing/Catalog/H3C_CAS/H3C_CAS/Technical_Documents/Configure___Deploy/User_Manuals/H3C_CAS_CVM_UG_E0785-21554/?CHID=1087104","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/h3c-cvm-unauthenticated-file-upload-via-fileupload-upload-token","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"yes","technical_impact":"total","assessed_at":"2026-10-05T15:48:14.146708Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-05T15:48:29.812Z","content_hash":"95440e0f249b7b7e0d066c3acf25880affbeed3b44755a7a317a344b6c72fe0a"}}
