Several vulnerabilities have been discovered in Moodle, an online course management system. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-4297 Multiple cross-site request forgery (CSRF) vulnerabilities have been discovered. CVE-2009-4298 It has been discovered that the LAMS module is prone to the disclosure of user account information. CVE-2009-4299 The Glossary module has an insufficient access control mechanism. CVE-2009-4301 Moodle does not properly check permissions when the MNET service is enabled, which allows remote authenticated servers to execute arbitrary MNET functions. CVE-2009-4302 The login/index_form.html page links to an HTTP page instead of using an SSL secured connection. CVE-2009-4303 Moodle stores sensitive data in backup files, which might make it possible for attackers to obtain them. CVE-2009-4305 It has been discovered that the SCORM module is prone to an SQL injection. Additionally, an SQL injection in the update_record function, a problem with symbolic links and a verification problem with Glossary, database and forum ratings have been fixed. For the stable distribution (lenny), these problems have been fixed in version 1.8.2.dfsg-3+lenny3. For the oldstable distribution (etch), there are no fixed packages available and it is too hard to backport many of the fixes. Therefore, we recommend to upgrade to the lenny version. For the testing distribution (squeeze) and the unstable distribution (sid), these problems have been fixed in version 1.8.2.dfsg-6. We recommend that you upgrade your moodle packages.
