Moodle — система управления образовательными электронными курсами

Multiple open redirect vulnerabilities in Moodle 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via vectors related to (1) backup/backupfilesedit.php, (2) comment/comment_post.php, (3) course/switchrole.php, (4) mod/wiki/filesedit.php, (5) tag/coursetags_add.php, or (6) user/files.php.

mod/forum/user.php in Moodle 1.9.x before 1.9.14, 2.0.x before 2.0.5, and 2.1.x before 2.1.2 allows remote authenticated users to discover the names of other users via unspecified vectors.

Moodle 2.2.x before 2.2.5 and 2.3.x before 2.3.2 allows remote authenticated users to bypass intended capability restrictions and perform certain topic changes by leveraging course-editing capabilities.

lib/formslib.php in Moodle 2.1.x before 2.1.4 and 2.2.x before 2.2.1 does not properly handle multiple instances of a form element, which has unspecified impact and remote attack vectors.

Moodle 2.1.x before 2.1.6 and 2.2.x before 2.2.3 allows remote authenticated users to bypass question:use* capability requirements and add arbitrary questions to a quiz via the questions feature.

The rc4encrypt function in lib/moodlelib.php in Moodle 1.9.x before 1.9.16, 2.0.x before 2.0.7, 2.1.x before 2.1.4, and 2.2.x before 2.2.1 uses a hardcoded password of nfgjeingjk, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by reading this script's source code within the open-source software distribution.

Cross-site scripting (XSS) vulnerability in lib/filelib.php in Moodle 2.0.x before 2.0.9, 2.1.x before 2.1.6, and 2.2.x before 2.2.3 allows remote authenticated users to inject arbitrary web script or HTML via an assignment submission with zip compression, leading to text/html rendering during a "download all" action.

blog/rsslib.php in Moodle 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 allows remote attackers to obtain sensitive information from site-level blogs by leveraging the guest role and reading an RSS feed.

The ip_in_range function in mnet/lib.php in MNET in Moodle 1.9.x before 1.9.15 uses an incorrect data type, which allows remote attackers to bypass intended IP address restrictions via an XMLRPC request.

rss/file.php in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not properly implement the use of RSS tokens for impersonation, which allows remote authenticated users to obtain sensitive block information by reading an RSS feed.
