Title: WebCT Campus Edition HTML Injection Vulnerability
Severity: MODERATE
Description:
WebCT Campus Edition is a course management system. It is used by colleges and universities to deliver course material and assessments via the web.
A vulnerability has been identified in the application that may allow a remote attacker to execute arbitrary HTML or script code in the browser of an unsuspecting user. This issue exists due to a failure of the application to properly sanitize user supplied form input.
This issue presents itself when the application is used with Microsoft Internet Explorer, which allows script code execution in a page via the @import url() function. A malicious user could supply malicious HTML or script code to the application via this method when posting a message on a forum, which would then be rendered in the browser of an unsuspecting user whenever the malicious message is viewed. It has also been reported that the file upload method is vulnerable to this issue as well.
By exploiting this vulnerability it may be possible to steal the unsuspecting user's cookie-based authentication credentials, as well as other sensitive information. Other attacks may also be possible.
WebCT Campus Edition version 4.1 is reported to be affected by this issue.
