SquirrelMail contains a flaw that will allow an attacker to inject arbitrary SQL code. The issue is due to the insufficient sanitizing of data in input sent to the "abook_database.php" script. This will allow an attacker to inject or manipulate SQL queries. By sending a specially-crafted URL containing malicious SQL code, a remote attacker could add, modify or delete user information in the back-end database.
