DESCRIPTION:
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.

SOLUTION:
Apply hotfix.

Version 6.x:
ftp://ftp.rockliffe.com/MailSite/6.1.22/Hotfixes/
