DiY-CMS contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate input passed via the url upon submission to the poll/add.php script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.

Currently, there are no known workarounds or vendor upgrades to correct this issue. However, snup of Vulnerability Labs has released an unofficial patch to address this vulnerability.

As with all third-party solutions, ensure they come from a reliable source and are permitted under your company's security policy.
