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.
