Description:
Some vulnerabilities have been reported in MegaBook, which can be exploited by malicious people to conduct script insertion attacks.

The vulnerabilities are caused due to missing validation of user input. This can eg. be exploited by including script code in an entry in the guest book, which will be executed in a user's browser session, when a malicious post is viewed.

Successful exploitation can result in disclosure of various information (eg. cookie-based authentication information) associated with the site running MegaBook or inclusion of malicious content, which the user thinks is part of the real website.

The vulnerabilities have been reported in version 2.0 and 2.1. Other versions may also be affected.

Solution:
Use another product.
