602LAN Suite contains a flaw that allows a remote attacker to enumerate arbitrary files outside of the web path. The issue is due to the mail script not properly sanitizing user input, specifically traversal style attacks (../../) supplied via the A variable, leading to loss of confidentiality. In addition, these requests could be scripted with the goal of consuming the server's resources, leading to a loss of availability.
