CVE reference:CVE-2006-1199
CVE-2006-1200


Description:
retard has discovered two vulnerabilities in Link Bank, which can be exploited by malicious people to conduct cross-site scripting attacks and compromise a vulnerable system.

1) Input passed to the "url_name" and "url" parameters when adding links isn't properly sanitised before being saved. This can be exploited to inject and execute arbitrary PHP code.

2) Input passed to the "site" parameter in "iframe.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.

The vulnerabilities have been confirmed in the latest available version. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised.

Provided and/or discovered by:
retard
