| Title | cskefu v8 Improper Input Validation |
|---|
| Description | A vulnerability was found in cskefu v8. This affects the function upload of the file com/cskefu/cc/controller/resource/MediaController.java. The manipulation of the Content-Type header during file upload leads to Stored Cross-Site Scripting (XSS). The application fails to validate uploaded files, allowing an attacker to upload a malicious HTML file with a text/html MIME type. The malicious JavaScript is executed when the file is subsequently requested via the /res/image endpoint. |
