This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 2) An error due to the application insecurely storing the IMS enterprise enrol file (imsenterprise-enrol.xml) can be exploited to disclose certain sensitive information. 3) Certain input is not properly sanitised by the media filter before being used. This can be exploited to insert arbitrary HTML and script code which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed. Successful exploitation of this vulnerability requires authentication. These vulnerabilities are reported in versions prior to 1.9.11 and 2.0.2. 4) An error due to the "$CFG->forceloginforprofiles" option not being enforced can be exploited to disclose information about course profiles via search engine indexes or guest user access. 5) Input passed via course tags is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 6) An error within the My Profile block when placed on pages in the user context can be exploited to disclose private information. 7) An error due to insecure default permissions of the "teacher" role providing delete capability can be exploited to delete courses. These vulnerabilities are reported in versions prior to 2.0.2 8) The application allows users to perform certain actions via HTTP requests without making proper validity checks to verify the requests. This can be exploited to manipulate RSS feeds or mark courses and activities as completed by tricking a user into visiting a malicious web site while being logged in to the application.
