[原文]Cross-site scripting (XSS) vulnerability in Tangora Portal CMS 4.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the action parameter in a search page, as demonstrated using (1) page1631.aspx and (2) page496.aspx.
Tangora Portcal CMS contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the "action" variable upon submission to the SiteSage portion of the product. 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.
