CVE-2006-3296

Description:
Moroccan Security Team has discovered two vulnerabilities in Open Guestbook, which can be exploited by malicious people to conduct cross-site scripting and SQL injection attacks.
1) Input passed to the "title" parameter in header.php isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) Input passed to the "offset" parameter in view.php isn't properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
The vulnerabilities have been confirmed in version 0.5. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly sanitised.
