MailBee WebMail XSS Vulnerabilities

Ivan Javier Sanchez has reported some vulnerabilities in MailBee WebMail, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "mode" parameter in login.php and to the "mode2" parameter in default.asp is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

The vulnerability is reported in versions prior to MailBee WebMail Pro ASP 3.4.64, MailBee WebMail Lite ASP 4.0.11, and MailBee WebMail Lite PHP 4.0.22.
