Improper Input Validation
function/update_xml.php in FLABER 1.1 and earlier allows remote attackers to overwrite arbitrary files by specifying the target filename in the target_file parameter. NOTE: this can be leveraged for code execution by overwriting a PHP file, as demonstrated using function/upload_file.php.
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.
