Improper Input Validation
An issue was discovered in Responsive Filemanager through 9.14.0. In the ajax_calls.php file in the save_img action in the name parameter, there is no validation of what kind of extension is sent. This makes it possible to execute PHP code if a legitimate JPEG image contains this code in the EXIF data, and the .php extension is used in the name parameter. (A potential fast patch is to disable the save_img action in the config file.)
CWE-20 - Improper Input Validation
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
