| Title | Great Developers Certificate Generator System 1.0 Unrestricted Upload |
|---|
| Description | An Arbitrary File Upload vulnerability (CWE-434) exists in the CSV upload functionality. The application validates uploaded files solely based on the file extension and concatenates the original filename directly into the destination path. This validation can be trivially bypassed by supplying a crafted filename such as payload.csv.php. No MIME type validation, file size restriction, or content inspection is performed. Uploaded files are stored in a web-accessible directory, enabling potential execution of malicious scripts if server-side execution is permitted. |
