[原文]Cross-site scripting (XSS) vulnerability in user_class.php in Papoo 2.1.4 and earlier allows remote attackers to inject arbitrary web script or HTML via the username field during the registration of a new account. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.
Papoo contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate "username" variable upon submission to the user_class.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 workarounds or upgrades to correct this issue. However, the vendor has released a patch to address this vulnerability.
