affects Moodle. 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.

Lifecycle Timeline
2DescriptionCVE.org
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.
Executive ViewAI
A critical authentication bypass vulnerability in Moodle's LTI Provider integration allows attackers to gain unauthorized access to learning management systems without valid credentials. This directly threatens user data confidentiality, institutional compliance obligations, and the integrity of educational records for any organization using Moodle with LTI integrations enabled.
Disable LTI Provider if not operationally critical; restrict LTI endpoint access via network firewall to known integrating systems only; implement WAF rules to filter suspicious LTI authentication requests; enforce additional authentication layers (IP whitelisting, certificate-based validation) for LTI connections; increase monitoring and alerting on LTI authentication events; segment LTI-enabled Moodle instances from critical infrastructure; require manual approval for LTI user creation.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
