Description

Vulnerability Description

PostNuke contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the "ttitle" variable upon submission to the Download module. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Solution Description

Upgrade to version 0.726.1 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
