[原文]Multiple cross-site scripting (XSS) vulnerabilities in Kayako liveResponse 2.x allow remote attackers to inject arbitrary web script or HTML via the (1) username parameter or (2) name field when entering a session or sending a message.
Kayako LiveResponse contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'username' variable upon submission to the index.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 and confidentiality
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
