Description

PHP contains a flaw that allows a remote attacker to traverse outside of a restricted path. The issue is due to the program not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) when a request is sent to upload multiple files. This directory traversal attack would allow the attacker to corrupt $_FILES indices.
