DESCRIPTION: Aliaksandr Hartsuyeu has discovered some vulnerabilities in B-net Software, which can be exploited by malicious people to conduct script insertion attacks.
Input passed to various fields when signing the guestbook and sending a message via the "Shoutbox" isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious user data is viewed.
The vulnerabilities have been confirmed in version 1.0. Other versions may also be affected.
SOLUTION: Edit the source code to ensure that input is properly sanitised.
