{"id":"UBUNTU-CVE-2022-45149","details":"A vulnerability was found in Moodle which exists due to insufficient validation of the HTTP request origin in course redirect URL. A user's CSRF token was unnecessarily included in the URL when being redirected to a course they have just restored. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website. This flaw allows an attacker to perform cross-site request forgery attacks.","modified":"2025-10-24T04:53:59Z","published":"2022-11-23T15:15:00Z","upstream":["CVE-2022-45149"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-45149"},{"type":"REPORT","url":"https://moodle.org/mod/forum/discuss.php?d=440769"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2142772"},{"type":"REPORT","url":"http://git.moodle.org/gw?p=moodle.git&a=search&h=HEAD&st=commit&s=MDL-75862"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-45149"}],"affected":[{"package":{"name":"moodle","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/moodle@3.0.3+dfsg-0ubuntu1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.7.9+dfsg-1","2.7.10+dfsg-1","2.7.11+dfsg-1","2.7.11+dfsg-2","2.7.12+dfsg-1","3.0.3+dfsg-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"moodle","binary_version":"3.0.3+dfsg-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-45149.json"}},{"package":{"name":"moodle","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/moodle@3.0.3+dfsg-0ubuntu1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.3+dfsg-0ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"moodle","binary_version":"3.0.3+dfsg-0ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-45149.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
