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 an SQL injection vulnerability in the Moodle Configurable Reports plugin before version 5.3.1. It allows low-privileged users who can view reports to inject malicious SQL code via the filter_var parameter in viewreport.php. Attackers can use subqueries or UNION SELECT statements to read arbitrary database tables, including sensitive user password hashes.

Detection Guidance

Check if the Configurable Reports plugin version is below 5.3.1. Inspect Moodle logs for suspicious SQL queries containing %%FILTER_VAR%% or UNION SELECT. Use tools like grep to search for these patterns in web server or database logs.

Impact Analysis

If exploited, this vulnerability could allow attackers to access sensitive data like user passwords, modify or delete database records, or perform unauthorized actions within the Moodle system. Attackers only need low-level access to view reports with the vulnerable placeholder.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR and HIPAA requirements for data protection and access controls. Organizations using vulnerable versions may face compliance violations, legal penalties, and reputational damage.

Mitigation Strategies

Upgrade the Configurable Reports plugin to version 5.3.1 or later immediately. If upgrading is not possible, disable the plugin or restrict access to the viewreport.php endpoint for low-privileged users.
