A security vulnerability was discovered in Moodle that allows students to enroll themselves in courses without completing all the necessary safety checks. Specifically, users can sign up for courses prematurely, even if they haven't finished two-step verification processes.
A vulnerability was found in Moodle. Additional checks are required to ensure users with permission to view badge recipients can only access lists of those they are intended to have access to.
A flaw was found in Moodle. Dynamic tables did not enforce capability checks, which resulted in users having the ability to retrieve information they did not have permission to access.
A vulnerability was found in Moodle. Additional checks are required to ensure users can only fetch the list of course badges for courses that they are intended to have access to.
A flaw was found in Moodle. When restricting access to a lesson activity with a password, certain passwords could be bypassed or less secure due to a loose comparison in the password-checking logic. This issue only affected passwords set to "magic hash" values.
Additional sanitizing was required when opening the equation editor to prevent a stored Cross-site Scripting (XSS) risk when editing another user's equation.
The site log report required additional encoding of event descriptions to ensure any HTML in the content is displayed in plaintext instead of being rendered.
ID numbers displayed in the lesson overview report required additional sanitizing to prevent a stored XSS risk.
Insufficient escaping of participants' names in the participants page table resulted in a stored XSS risk when interacting with some features.
Incorrect validation of allowed event types in a calendar web service made it possible for some users to create events with types/audiences they did not have permission to publish to.
Moodle through 2.6.11, 2.7.x before 2.7.11, 2.8.x before 2.8.9, and 2.9.x before 2.9.3 does not consider the moodle/badges:viewbadges capability, which allows remote authenticated users to obtain sensitive badge information via a request involving (1) badges/overview.php or (2) badges/view.php.
A vulnerability was found in moodle before version 3.6.3. The getwithcapabilityjoin and getusersbycapability functions were not taking context freezing into account when checking user capabilities
In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user with both access to restore database activity modules and direct access to the web server outside of the Moodle webroot could execute a local file include.
lib/filelib.php in Moodle through 2.2.11, 2.3.x before 2.3.10, 2.4.x before 2.4.7, and 2.5.x before 2.5.3 does not send "Cache-Control: private" HTTP headers, which allows remote attackers to obtain sensitive information by requesting a file that had been previously retrieved by a caching proxy server.
A flaw was found in moodle. Insufficient capability checks make it possible for users with access to restore glossaries in courses to restore them into the global site glossary.
A flaw was found in moodle. Matrix room membership and power levels are incorrectly applied and revoked for suspended Moodle users.
A flaw was found in moodle. The cURL wrapper in Moodle strips HTTPAUTH and USERPWD headers during emulated redirects, but retains other original request headers, so HTTP authorization header information could be unintentionally sent in requests to redirect URLs.
A flaw was found in moodle. External API access to Quiz can override contained insufficient access control.
A flaw was found in moodle. Some hidden user profile fields are visible in gradebook reports, which could result in users without the "view hidden user fields" capability having access to the information.
In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user with both access to restore wiki modules and direct access to the web server outside of the Moodle webroot could execute a local file include.
In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user with both access to restore workshop modules and direct access to the web server outside of the Moodle webroot could execute a local file include.
In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user with both access to restore feedback modules and direct access to the web server outside of the Moodle webroot could execute a local file include.
The Chat activity in Moodle 4.3.3 allows students to insert a potentially unwanted HTML A element or IMG element, or HTML content that leads to a performance degradation. NOTE: the vendor's UsingChat page says "If you know some HTML code, you can use it in your text to do things like insert images, play sounds or create different coloured and sized text." This page also says "Chat is due to be removed from standard Moodle."
A Cross-Site Scripting (XSS) vulnerability exists in the way MOODLE 3.10.9 handles user input within the "GET /?lang=" URL parameter.
A flaw was found in moodle. H5P error messages require additional sanitizing to prevent a reflected cross-site scripting (XSS) risk.
A flaw was found in moodle. Insufficient sanitizing of data when performing a restore could result in a cross-site scripting (XSS) risk from malicious backup files.
Cross-site scripting (XSS) vulnerability in flashuploader.swf in the Uploader component in Yahoo! YUI 3.5.0 through 3.9.1, as used 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, 2.5.x before 2.5.1, and other products, allows remote attackers to inject arbitrary web script or HTML via a crafted string in a URL.
Cross-site scripting (XSS) vulnerability in uploader.swf in the Uploader component in Yahoo! YUI 3.2.0 through 3.9.1, as used 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, 2.5.x before 2.5.1, and other products, allows remote attackers to inject arbitrary web script or HTML via a crafted string in a URL.
comment/lib.php in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 does not properly restrict comment capabilities, which allows remote attackers to post a comment by leveraging the guest role and operating on a front-page activity.
Multiple cross-site scripting (XSS) vulnerabilities in the media-filter implementation in filter/mediaplugin/filter.php in Moodle 1.9.x before 1.9.11 and 2.0.x before 2.0.2 allow remote attackers to inject arbitrary web script or HTML via vectors involving (1) Flash Video (aka FLV) files and (2) YouTube videos.
