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.
A flaw was found in Moodle. This cross-site scripting (XSS) vulnerability, caused by improper sanitization of AI prompt responses, allows attackers to inject malicious HTML or script into web pages. When other users view these compromised pages, their sessions could be stolen, or the user interface could be manipulated.
A flaw was found in Moodle. This authentication bypass vulnerability allows suspended users to authenticate through the Learning Tools Interoperability (LTI) Provider. The issue arises from the LTI authentication handlers failing to enforce the user's suspension status, enabling unauthorized access to the system. This can lead to information disclosure or other unauthorized actions by users who should be restricted.
A flaw was found in Moodle. An attacker with access to the restore interface could trigger server-side execution of arbitrary code. This is due to insufficient validation of restore input, which leads to unintended interpretation by core restore routines. Successful exploitation could result in a full compromise of the Moodle application.
An issue in Moodle’s timed assignment feature allowed students to bypass the time restriction, potentially giving them more time than allowed to complete an assessment.
A flaw in the cohort search web service allowed users with permissions in lower contexts to access cohort information from the system context, revealing restricted administrative data.
Moodle exposed the names of hidden groups to users who had permission to create calendar events but not to view hidden groups. This could reveal private or restricted group information.
Moodle’s mobile and web service authentication endpoints did not sufficiently restrict repeated password attempts, making them susceptible to brute-force attacks.
A serious authentication flaw allowed attackers with valid credentials to bypass multi-factor authentication under certain conditions, potentially compromising user accounts.
The router’s inconsistent response to invalid course IDs allowed attackers to infer which course IDs exist, potentially aiding reconnaissance.
An error-handling issue in the Moodle router (r.php) could cause the application to display internal directory listings when specific HTTP headers were not properly configured.
Moodle failed to verify enrolment status correctly when sending quiz notifications. As a result, suspended or inactive users might receive quiz-related messages, leaking limited course information.
A flaw was found in the course overview output function where user access permissions were not fully enforced. This could allow unauthorized users to view information about courses they should not have access to, potentially exposing limited course details.
A session fixation vulnerability in Moodle 3.x through 3.11.18 allows unauthenticated attackers to hijack user sessions via the sesskey parameter. The sesskey can be obtained without authentication and reused within the OAuth2 login flow, resulting in the victim's session being linked to the attacker's. Successful exploitation results in full account takeover. According to the Moodle Releases page, "Bug fixes for security issues in 3.11.x ended 11 December 2023." NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
A flaw has been identified in Moodle where insufficient capability checks in certain grade reports allowed users without the necessary permissions to access hidden grades.
A flaw has been identified in Moodle where, on certain sites, unauthenticated users could retrieve sensitive user data—including names, contact information, and hashed passwords—via stack traces returned by specific API calls. Sites with PHP configured with zend.exception_ignore_args = 1 in the php.ini file are not affected by this vulnerability.
A flaw was discovered in Moodle. Additional checks were required to ensure that users can only access cohort data they are authorized to retrieve.
A flaw was found in Moodle. Insufficient capability checks in a messaging web service allowed users to view other users' names and online statuses.
