SquirrelMail latest version (although is tested on version 1.4.2) is prone to many cross scripting attacks that can be used to steal user cookies.The Exploit lies in the way squirrel mail represents the folder names and shows them.To make the matters worse.No extra unique variable added to the url for each user therefore it is easy for the attacker to just pass the url in mail and steal the session cookie.
Some of the exploit are at :
http://victim.com/mail/src/compose.php?mailbox=INBOX
which can be replaced as follows
http://victim.com/mail/src/compose.php?mailbox="><script>malacious script</script>
Example:
http://victim.com/mail/src/compose.php?mailbox="><script>window.alert(document.cookie)</script>
