TITLE:
SmarterMail Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA11042

VERIFY ADVISORY:
http://secunia.com/advisories/11042/

CRITICAL:
Less critical

IMPACT:
Cross Site Scripting, Exposure of sensitive information, DoS

WHERE:
From remote

SOFTWARE:
SmarterMail

DESCRIPTION:
Dr_insane has reported some vulnerabilities in SmartMail, allowing
malicious people to cause a Denial of Service, view the contents of
arbitrary files, and potentially conduct Cross Site Scripting
attacks.

1) Input to the "filename" parameter in "frmGetAttachment.aspx" isn't
properly verified before it is used to open files. This can be
exploited by supplying the classic directory traversal character
sequence "../" in the URL to view the contents of arbitrary files.

2) Input to the "txtusername" in "login.aspx" isn't properly
verified.

3) The SMTP service fails to handle multiple connections. This can be
exploited to cause the service to consume 100% CPU resources by
making more than 600 connections.

4) Input to the spell checker from "frmCompose.aspx" isn't properly
verified. This can potentially be exploited to inject arbitrary
script and HTML code.

SOLUTION:
Filter access to ensure that only trusted IP addresses can connect to
the services.
