Ghost Hacker has discovered a security issue in hyBook Guestbook Script, which can be exploited by malicious people to disclose potentially sensitive information.

The security issue is caused due to the "hyBook.mdb" database being stored with insecure permissions inside the web root. This can be exploited to gain knowledge of potentially sensitive information by downloading the file.

Solution
Move the database file out of the web root.
