Microsoft Sharepoint Upload.aspx cross-site scripting
|sharepoint-aspx-xss (56597)||Medium Risk|
Microsoft Sharepoint is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Upload.aspx script within the Documents module. A remote authenticated attacker could exploit this vulnerability using an uploaded TXT file to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
Upgrade to the latest version of SharePoint Server (2010 or later), available from the Microsoft Office SharePoint Server Web site. See References.

- CVE-2010-0716: _layouts/Upload.aspx in the Documents module in Microsoft SharePoint before 2010 uses URLs with the same hostname and port number for a web site's primary files and individual users' uploaded files (aka attachments), which allows remote authenticated users to leverage same-origin relationships and conduct cross-site scripting (XSS) attacks by uploading TXT files, a related issue to CVE-2008-5026. NOTE: the vendor disputes the significance of this issue, because cross-domain isolation can be implemented when needed.
