Description

Several vulnerabilities have been discovered in Moodle, an online course management system. The Common Vulnerabilities and Exposures project identifies the following problems :

  • CVE-2009-0500 It was discovered that the information stored in the log tables was not properly sanitized, which could allow attackers to inject arbitrary web code.

  • CVE-2009-0502 It was discovered that certain input via the 'Login as' function was not properly sanitised leading to the injection of arbitrary web script.

  • CVE-2008-5153 Dmitry E. Oboukhov discovered that the SpellCheker plugin creates temporary files insecurely, allowing a denial of service attack. Since the plugin was unused, it is removed in this update.
