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.","published":"2026-10-02T19:16:38.897","modified":"2026-10-02T19:16:38.897","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://blog.csdn.net/qq_41904294/article/details/134697278"},{"type":"WEB","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/h3c-cvm-arbitrary-file-upload.yaml"},{"type":"WEB","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"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/h3c-cvm-unauthenticated-file-upload-via-fileupload-upload-token"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-02T19:16:38.897"}}
