What is CVE-2020-10567?

CVE-2020-10567 is a critical vulnerability in n/a, published on 14 Mar 2020. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

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.)
