PHP is vulnerable to authorization bypass. File names with NULL characters \0 are not properly handled, which would allow a remote attacker to abuse the vulnerability to create a PHP script to access arbitrary files and bypass file system access restrictions. This is demonstrated by entering a NULL character such as .php\0.jpg at the end of the argument to the file_exists function, which causes access controls to treat the file as an image .jpg file, but process the file as a .php file.
