SQL Injection in MCMS through FreeMarker Template

Publication date: 2026-08-26

Last updated on: 2026-09-01

Assigner: MITRE

Description
The front-end interface /cms/category/list of MCMS <=6.2.0 is vulnerable to SQL injection. The size parameter is directly concatenated into the LIMIT clause of SQL through FreeMarker ${size} without being parameterized and bound. The built-in SqlInjectionUtil employs regular expression blacklist filtering, yet keywords like CREATE/TABLE/SET/PREPARE/EXECUTE are not included in the list, allowing for bypassing. Attackers can execute stacked SQL statements without logging in.

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 vulnerability is a SQL injection flaw in the front-end interface /cms/category/list of MCMS version 6.2.0 or earlier. The issue occurs because the size parameter is directly inserted into the SQL LIMIT clause without proper sanitization or parameterization. Attackers can exploit this to inject malicious SQL code, including stacked statements, without authentication.

Detection Guidance

To detect this SQL injection vulnerability in MCMS <=6.2.0, inspect HTTP requests to /cms/category/list for the size parameter. Test by appending SQL payloads like size=1;SHOW TABLES-- to observe database responses. Use tools like sqlmap with --data='size=1' to automate detection.

Impact Analysis

An attacker could exploit this to read, modify, or delete sensitive data in the database, execute administrative operations, or bypass authentication. Since no login is required, any user accessing the vulnerable interface could be at risk of unauthorized database access or manipulation.

Compliance Impact

This vulnerability could lead to unauthorized data access or exposure, violating GDPR's data protection principles and HIPAA's security requirements for protected health information. Organizations using affected MCMS versions may face compliance violations, legal penalties, and reputational damage due to potential data breaches.

Mitigation Strategies

Immediately upgrade MCMS to a version beyond 6.2.0 if available. If not, apply input validation to sanitize the size parameter, blocking special characters. Disable stacked queries in your database configuration. Monitor logs for suspicious requests to /cms/category/list.
