Aliaksandr Hartsuyeu has discovered a vulnerability in Chipmunk
GuestBook, which can be exploited by malicious people to conduct
script insertion attacks.
Input passed to the homepage field when signing the guestbook 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
guestbook entry is viewed.
The vulnerability has been confirmed in version 1.4. Other versions
may also be affected.
SOLUTION:
Edit the source code to ensure that input is properly sanitised.
