Inspur Haiyue HCM Cloud contains an arbitrary file read vulnerability in the /api/model_report/file/download endpoint that allows unauthenticated remote attackers to read arbitrary files by supplying unvalidated path parameters index and ext. Attackers can craft requests such as /api/model_report/file/download?index=/&ext=<path> to traverse the filesystem and disclose sensitive files including /etc/passwd, application database files, and system configuration files. Exploitation evidence was first observed by the Shadowserver Foundation on 2024-11-04 .
