[原文]Cross-site scripting (XSS) vulnerability in default.php in Clever Copy 3.0 allows remote attackers to inject arbitrary web script or HTML via the Subject field when sending private messages (privatemessages.php). NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Clever Copy contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'Subject' variable upon submission to the privatemessages.php script. 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.
