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 Authenticated SQL Injection vulnerability in Woltlab WCF versions 6.2.4 and earlier. It allows authenticated users to execute arbitrary SQL commands by manipulating the updateUserOptions function in UserEditor.class.php and the update action in UserAction.class.php. This can lead to unauthorized data access or modification in the database.

Detection Guidance

To detect this SQL injection vulnerability in WoltLab WCF versions before 6.2.5, inspect web server logs for suspicious database query patterns or unauthorized user option updates. Check for requests targeting UserEditor.class.php or UserAction.class.php with unusual parameters. Monitor for unexpected database access or privilege escalation attempts by authenticated users.

Impact Analysis

An attacker with valid credentials could exploit this to read sensitive data from the database, such as user credentials, personal information, or other confidential data. If privileged accounts lack two-factor authentication, attackers may gain elevated access, potentially compromising the entire system.

Compliance Impact

This vulnerability could lead to unauthorized access to personal data, violating GDPR requirements for data protection and user privacy. For HIPAA, it may risk exposure of protected health information if such data is stored in the affected system. Compliance failures could result in legal penalties and reputational damage.

Mitigation Strategies

Update WoltLab Suite to versions 6.2.5, 6.1.22, 6.0.26, or 5.5.26 or later to patch the SQL Injection vulnerability. Ensure all users enable Two-Factor Authentication (2FA) to prevent unauthorized access even if the vulnerability is exploited.
