Detailed vulnerability description
The vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to an error when the move_uploaded_file implementation in ext/standard/basic_functions.c in PHP before 5.4.39, 5.5.x before 5.5.23, and 5.6.x before 5.6.7 truncates a pathname upon encountering a x00 character. A remote attacker can bypass intended extension restrictions and create files with unexpected names via a crafted second argument.
