[原文]Multiple cross-site scripting (XSS) vulnerabilities in Wordcircle 2.17 allow remote attackers to inject arbitrary web script or HTML via (1) the "Course name" field in index.php when the frm parameter has the value "mine" and (2) possibly certain other fields in unspecified scripts.
wordcircle contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the content of the 'Course Name' field 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.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
