Title: Chipmunk Guestbook Homepage HTML Injection Vulnerability
Severity: MODERATE
Description:
Chipmunk Guestbook is a guestbook application that is implemented in PHP.
Chipmunk Guestbook is prone to an HTML injection vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input to the 'Homepage' field of the 'addentry.php' script before using it in dynamically generated content.
Attacker-supplied HTML and script code would be executed in the context of the affected Web site, potentially allowing for theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.
Affected Products:
- Chipmunk Guestbook 1.4.0
