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.","state":0,"publishedAt":"2026-10-02T18:36:03.442+00:00","modifiedAt":"2026-10-05T15:48:29.812+00:00","affected":[{"ecosystem":"Vendor product","name":"CVM","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"H3C\",\n                    \"product\": \"CVM\",\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:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/h3c-cvm-arbitrary-file-upload.yaml","https://blog.csdn.net/qq_41904294/article/details/134697278","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","https://www.vulncheck.com/advisories/h3c-cvm-unauthenticated-file-upload-via-fileupload-upload-token"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-54405","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-54405","identifiers":["CVE-2023-54405"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
