CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a SQL injection vulnerability in Moodle. An authenticated attacker with access to the question bank web service can submit unsanitized input into database queries. This allows them to manipulate or extract sensitive data from the database.

Detection Guidance

To detect this SQL injection vulnerability in Moodle, inspect web service logs for suspicious input patterns in the question bank web service. Check for unsanitized SQL queries or unusual database access. Use tools like SQLMap to test for injection points in the web service endpoints. Monitor database logs for unauthorized queries or data manipulation attempts.

Impact Analysis

An attacker could view, alter, or delete sensitive data stored in the database. This includes unauthorized code execution, data confidentiality loss, privilege escalation, bypassing protection mechanisms, and data integrity compromise.

Compliance Impact

This vulnerability could lead to unauthorized access, alteration, or deletion of sensitive data stored in the database, which may violate compliance requirements under GDPR and HIPAA. Unauthorized data exposure or manipulation could result in legal penalties, loss of trust, and failure to meet regulatory standards for data protection and integrity.

Mitigation Strategies

Immediately update Moodle to the latest version to patch the vulnerability. Restrict access to the question bank web service to only necessary users with minimal required privileges. Implement input validation and parameterized queries to sanitize all user inputs. Review and audit database access logs for any signs of exploitation.
