Description:
A vulnerability and a weakness have been reported in Blackboard Learning and Community Portal Systems, which can be exploited by malicious users to conduct script insertion attacks and by malicious people to potentially conduct phishing attacks.
1) The weakness is caused due to a design error in the way Blackboard Learning and Community Portal Systems displays an unverified user supplied argument (url) in its own frameset after successful authentication. This can e.g. be exploited by tricking a user into following a link from a HTML document to the trusted login page with a malicious "TARGET" URL. After successful authentication, the untrusted (fake) site will be displayed in the frameset of the trusted site.
Example:
http://[host]/webapps/portal/frameset.jsp?tab_id=[tabid]&url=[url]
The vulnerability has been reported in version 6.2.3.23 and 6.3.1.424 . Other versions may also be affected.
2) Input passed to parameters to "Essay questions" in the "Test" section of courses is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.
The vulnerability has been reported in version 6.2.3.23 . Other versions may also be affected.
