Title: EJ3 BlackBook Information Disclosure Vulnerability
Severity: MODERATE
Description:
BlackBook is a Web-based guestbook system written in PHP.
It has been reported that the BlackBook installation routine does not properly set filesystem permissions on the /blackbook/data/data.dat file. This file contains posts made to the guestbook, as well as associated usernames and IP addresses for each post. Users may be able to read this file and subsequently retrieve sensitive information associated with a given user.
It should be noted that even though the setup procedure indicates permissions are being set, the operation may not be successful. This would leave the files exposed to unauthorized users.
Affected Products:
- EJ3 BlackBook 1.0.0
