| Description | An unrestricted file upload vulnerability in FastapiAdmin (≤ 2.2.0) at /api/v1/common/file/upload allows authenticated users with the module_common:file:upload permission to write arbitrary files to the server filesystem and, when combined with the scheduled task APIs, achieve remote code execution; the upload routine trusts the Content-Type header to infer allowed extensions, does not validate or canonicalize file paths, and writes files directly under the upload directory, enabling attackers to bypass extension checks (e.g., upload a Python script disguised as an SVG), persist it, and trigger execution via task scheduling. Mitigations include enforcing server-side content inspection (validate file magic bytes), deriving extensions from content not headers, normalizing and restricting saved paths to a safe upload directory with no execute permissions, generating safe randomized filenames, imposing strict allowlists for upload types, scanning uploads for dangerous content, and requiring least-privilege access controls and audit logging for upload and task APIs. |
