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."}],"tags":["x_known-exploited-vulnerability"],"datePublic":"2023-10-14T00:00:00.000Z","problemTypes":[{"descriptions":[{"lang":"en","cweId":"CWE-434","description":"Unrestricted Upload of File with Dangerous Type","type":"CWE"}]}],"affected":[{"defaultStatus":"unknown","vendor":"H3C","product":"CVM","versions":[{"status":"affected","version":"*","versionType":"custom"}]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV4_0":{"attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"HIGH","subConfidentialityImpact":"NONE","vulnIntegrityImpact":"HIGH","subIntegrityImpact":"NONE","vulnAvailabilityImpact":"HIGH","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED","version":"4.0","baseSeverity":"CRITICAL","baseScore":9.3,"vectorString":"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"}},{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH","version":"3.1","baseSeverity":"CRITICAL","baseScore":9.8,"vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}}],"references":[{"url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/h3c-cvm-arbitrary-file-upload.yaml","name":"Nuclei Template","tags":["technical-description"]},{"url":"https://blog.csdn.net/qq_41904294/article/details/134697278","name":"CSDN Blog","tags":["technical-description","exploit"]},{"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","name":"Product Documentation","tags":["product"]},{"url":"https://www.vulncheck.com/advisories/h3c-cvm-unauthenticated-file-upload-via-fileupload-upload-token","tags":["third-party-advisory"]}],"credits":[{"lang":"en","value":"The Shadowserver Foundation","type":"reporter"}],"source":{"discovery":"UNKNOWN"},"x_generator":{"engine":"vulncheck"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-05T15:48:14.146708Z","id":"CVE-2023-54405","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-05T15:48:29.812Z"}}]}}
