Description:
Secunia Research has discovered some vulnerabilities in MailEnable Web Mail Client, which can be exploited by malicious people to conduct cross-site request forgery attacks, cross-site scripting attacks, and script insertion attacks.

1) Scripts in email messages are not properly sanitised before being used to display the email message. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when a user views a specially crafted email message.

2) Input passed to the "ID" parameter in mewebmail/base/default/lang/EN/right.asp, mewebmail/base/default/lang/EN/Forms/MAI/list.asp, and mewebmail/base/default/lang/EN/Forms/VCF/list.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.

Successful exploitation requires that the target user is logged in.

3) The application allows users to send messages via HTTP requests without performing any validity checks to verify the request. This can be exploited to change a user's settings by e.g. tricking a target user into visiting a malicious website.

The vulnerabilities are confirmed in version MailEnable Professional 2.351. Other versions may also be affected.

Solution:
MailEnable Enterprise 2.x:
Update to version 2.37.

MailEnable Professional 2.x:
Update to version 2.37.

MailEnable Enterprise 1.x:
Update to version 1.42.

MailEnable Professional 1.x:
Update to version 1.85.
