[原文]Cross-site scripting (XSS) vulnerability in the Downloads module in PostNuke up to 0.726, and possibly later versions, allows remote attackers to inject arbitrary HTML and web script via the ttitle parameter in a viewdownloaddetails action.
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.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
