Input passed via the "name", "description", and "location" parameters to edit_entry_handler.php is not properly sanitised before being displayed to the user. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed. The vulnerabilities are confirmed in version 1.2.3. Other versions may also be affected. SOLUTION: Edit the source code to ensure that input is properly sanitised.
