A denial-of-service vulnerability was identified in Moodle’s TeX formula editor. When rendering TeX content using mimetex, insufficient execution time limits could allow specially crafted formulas to consume excessive server resources. An authenticated user could abuse this behavior to degrade performance or cause service interruption.

A vulnerability was found in a Moodle TeX filter administrative setting where insufficient sanitization of configuration input could allow command injection. On sites where the TeX filter is enabled and ImageMagick is installed, a maliciously crafted setting value entered by an administrator could result in unintended system command execution. While exploitation requires administrative privileges, successful compromise could affect the entire Moodle server.

A flaw was identified in Moodle’s backup restore functionality where specially crafted backup files were not properly validated during processing. If a malicious backup file is restored, it could lead to unintended execution of server-side code. Since restore capabilities are typically available to privileged users, exploitation requires authenticated access. Successful exploitation could result in full compromise of the Moodle server.

A flaw was found in moodle. During anonymous assignment submissions, user identifiers were inadvertently exposed in URLs. This data exposure allows unauthorized viewers to see internal user IDs, compromising the intended anonymity and potentially leading to information disclosure.

A flaw was found in Moodle. An authorization logic flaw, specifically due to incomplete role checks during the badge awarding process, allowed badges to be granted without proper verification. This could enable unauthorized users to obtain badges they are not entitled to, potentially leading to privilege escalation or unauthorized access to certain features.

A flaw was found in mooodle. A remote attacker could exploit a reflected Cross-Site Scripting (XSS) vulnerability in the policy tool return URL. This vulnerability arises from insufficient sanitization of URL parameters, allowing attackers to inject malicious scripts through specially crafted links. Successful exploitation could lead to information disclosure or arbitrary client-side script execution within the user's browser.

A flaw was found in Moodle. An open redirect vulnerability in the OAuth login flow allows a remote attacker to redirect users to attacker-controlled pages after they have successfully authenticated. This occurs due to insufficient validation of redirect parameters, which could lead to phishing attacks or information disclosure.

A flaw was found in moodle. This formula injection vulnerability occurs when data fields are exported without proper escaping. A remote attacker could exploit this by providing malicious data that, when exported and opened in a spreadsheet, allows arbitrary formulas to execute. This can lead to compromised data integrity and unintended operations within the spreadsheet.

A flaw was found in moodle. This vulnerability, known as Cross-Site Scripting (XSS), occurs due to insufficient checks on user-provided data in the formula editor's arithmetic expression fields. A remote attacker could inject malicious code into these fields. When other users view these expressions, the malicious code would execute in their web browsers, potentially compromising their data or leading to unauthorized actions.
