Moodle: pix helper potential mustache code injection risk

The Mustache pix helper contained a potential Mustache injection risk if combined with user input (note: This did not appear to be implemented/exploitable anywhere in the core Moodle LMS).

Moodle: algebra filter xss when filter is misconfigured

If the algebra filter was enabled but not functional (eg the necessary binaries were missing from the server), it presented an XSS risk.

Moodle: authenticated arbitrary file read through malformed backup file

Insufficient sanitizing in backup resulted in an arbitrary file read risk. The capability to access this feature is only available to teachers, managers and admins by default.

Moodle: authenticated sql injection via availability check

Insufficient validation of profile field availability condition resulted in an SQL injection risk (by default only available to teachers and managers).

Moodle: possible to set the preferred "start page" of other users

The vulnerability was found Moodle which exists due to insufficient limitations on the "start page" preference. A remote attacker can set that preference for another user. The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

Moodle: reflected xss risk in blog search

The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in blog search. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a remote attacker to perform cross-site scripting (XSS) attacks.

Moodle: reflected xss risk in some returnurl parameters

The vulnerability was found Moodle which exists due to insufficient sanitization of user-supplied data in some returnurl parameters. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website. This flaw allows a remote attacker to perform cross-site scripting (XSS) attacks.

Moodle: course participation report shows roles the user should not see

The course participation report required additional checks to prevent roles being displayed which the user did not have access to view.

A reflected XSS issue was identified in the LTI module of Moodle. The vulnerability exists due to insufficient sanitization of user-supplied data in the LTI module. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website to steal potentially sensitive information, change appearance of the web page, can perform phishing and drive-by-download attacks. This vulnerability does not impact authenticated users.

An open redirect issue was found in Moodle due to improper sanitization of user-supplied data in mobile auto-login feature. A remote attacker can create a link that leads to a trusted website, however, when clicked, it redirects the victims to arbitrary URL/domain. Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.

A stored XSS and blind SSRF vulnerability was found in Moodle, occurs due to insufficient sanitization of user-supplied data in the SCORM track details. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website to steal potentially sensitive information, change appearance of the web page, can perform phishing and drive-by-download attacks.

The vulnerability was found in Moodle, occurs due to input validation error when importing lesson questions. This insufficient path checks results in arbitrary file read risk. This vulnerability allows a remote attacker to perform directory traversal attacks. The capability to access this feature is only available to teachers, managers and admins by default.

The vulnerability was found in Moodle, occurs due to improper input validation when parsing PostScript code. An omitted execution parameter results in a remote code execution risk for sites running GhostScript versions older than 9.50. Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
