IBM WebSphere Application Server (WAS) 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., ../../). This directory traversal attack would allow the attacker to overwrite arbitrary files.
