Rahul Mohandas has reported two vulnerabilities in MailSite Email Server, which can be exploited by malicious people to conduct cross-site scripting attacks and cause a DoS (Denial of Service).

1) Input passed in the url to the HTTP Mail Management Agent isn't properly sanitised before being returned to the user in an error message. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of a vulnerable site.

Example:
http://[host]:90/CGI-BIN/WCONSOLE.DLL?[code]

The vulnerability has been reported in version 5.x and 6.1.22. Prior versions may also be affected.

2) An error in the HTTP Management Agent when performing input validation can be exploited to crash the service via specially crafted parameters passed to "/CGI-BIN/WCONSOLE.DLL"

The vulnerability has been reported in version 7.0.3.1. Prior versions may also be affected.
