For Squirrelmail: Here are some important notes from the slide: * Default plugin <mail_fetch>, emulates POP3 fetcher with fsockopen() PHP functions, Post Authentication only - No verification on IP / PORTS * You can transform SquirrelMail as a kind of Nmap scanner This has been assigned TEHTRI-SA-2010-009 by the discoverer. The danger is that this attack could be used to bypass a firewall. Let's use CVE-2010-1637 for Squirrelmail. For Horde: * You can transform a default Horde installation to a kind of advanced network TCP scanner with banner grabbing, etc Pre-auth TEHTRI-SA-2010-010 Let's use CVE-2010-1638 for Horde If anyone has more links or information for these, please pass them along. Thanks. -- JB
