{"id":"CVE-2023-54405","published":"2026-10-02T19:16:38.897","lastModified":"2026-10-06T16:08:43.180","description":"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.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-434"],"vendors":[],"products":[],"references":[{"url":"https://blog.csdn.net/qq_41904294/article/details/134697278","tags":[]},{"url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/h3c-cvm-arbitrary-file-upload.yaml","tags":[]},{"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":[]},{"url":"https://www.vulncheck.com/advisories/h3c-cvm-unauthenticated-file-upload-via-fileupload-upload-token","tags":[]}],"exploitRefs":[{"url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/h3c-cvm-arbitrary-file-upload.yaml","tags":[]}],"hasPoc":true,"ai":{"summary":"This vulnerability allows unauthenticated attackers to upload arbitrary files, potentially leading to remote code execution.","exploitability":"Exploitation is relatively straightforward as it requires manipulating a token parameter to upload a malicious JSP file.","blast_radius":"If exploited, attackers could gain full control over the web server, leading to significant damage.","remediation":"Disable the affected /cas/fileUpload/upload endpoint or restrict access to it.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","web","upload","unauth"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-03T08:45:14.282Z"}}
