Tecrail Responsive FileManager any version

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.)

In Responsive Filemanager < 9.12.0, an attacker can bypass upload restrictions resulting in RCE.

Tecrail Responsive Filemanger path traversal

An issue in Tecrail Responsive FileManager v9.9.5 and below allows attackers to bypass the file extension check mechanism and upload a crafted PHP file, leading to arbitrary code execution.

/filemanager/ajax_calls.php in tecrail Responsive FileManager before 9.13.4 uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize get_file sequences such as ".." that can resolve to a location that is outside of that directory, aka Directory Traversal.

/filemanager/upload.php in Responsive FileManager before 9.13.3 allows Directory Traversal and SSRF because the url parameter is used directly in a curl_exec call, as demonstrated by a file:///etc/passwd value.

An issue was discovered in Responsive Filemanager through 9.14.0. In the dialog.php page, the session variable $_SESSION['RF']["view_type"] wasn't sanitized if it was already set. This made stored XSS possible if one opens ajax_calls.php and uses the "view" action and places a payload in the type parameter, and then returns to the dialog.php page. This occurs because ajax_calls.php was also able to set the $_SESSION['RF']["view_type"] variable, but there it wasn't sanitized.

/filemanager/ajax_calls.php in tecrail Responsive FileManager before 9.13.4 does not properly validate file paths in archives, allowing for the extraction of crafted archives to overwrite arbitrary files via an extract action, aka Directory Traversal.
