Description:
matrix_killer has discovered a vulnerability in G-Book, which can be exploited by malicious people to conduct script insertion attacks.
Input passed to the "g_message" parameter in guestbook.php isn't sanitised before being stored as a guestbook entry. This can be exploited to execute arbitrary HTML and script code in the administrator user's and the user's browser session in context of an affected website when a malicious guestbook entry is viewed.
