SOFTWARE:

DESCRIPTION:
Nenad Vijatov has discovered a vulnerability in Merak Mail Server,
which can be exploited by malicious people to conduct script
insertion attacks.

Input passed via "<IMG>" HTML tags in emails is not properly
sanitised before being displayed. This can be exploited to insert
arbitrary HTML and script code via a specially crafted email, which
is executed in a user's browser session in context of an affected
site when the email is viewed.

The vulnerability is confirmed in version 9.3.2 for Windows. Other
versions may also be affected.

SOLUTION:
Update to version 9.4.0, which fixes the vulnerability in the WebMail
Pro Interface.

Development for "IceWarp Web Mail" and the  WebMail Basic interface
has been discontinued.
