Morinex Eneco has reported a vulnerability in Skull-Splitter's PHP Guestbook, which can be exploited by malicious people to conduct script insertion attacks.

Input passed to title or content of a message is not 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 guestbook entry is viewed.

The vulnerability has been reported in version 1.0, 2.0 and 2.2. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly sanitised.
