Flash files distributed with the YUI library in Moodle before 2.4.5 may have allowed for cross-site scripting attacks (MSA-13-0025). Privacy settings for the IMS-LTI (External tool) module in Moodle before 2.4.5 were not able to be changed so personal information was always transferred (MSA-13-0026).

It was possible to determine answers from ID values in Lesson activity matching questions in Moodle before 2.4.5 (CVE-2013-2243). Conditional access rule values for user fields were able to contain unescaped HTML/JS that would be output to users in Moodle before 2.4.5 (CVE-2013-2244). When impersonating another user using RSS tokens in Moodle before 2.4.5, an error was displayed, but block information relevant to the person being impersonated was shown (CVE-2013-2245). The Feedback module in Moodle before 2.4.5 was showing personal information to users without the needed capability (CVE-2013-2246).
