Description
An SQL injection vulnerability in CiviCRM through 6.18.alpha1 allows authenticated staff to read the entire database via the contact search RLIKE clause. The clause concatenates a user-supplied value into the SQL query without sanitization. An attacker with staff-level access can exfiltrate all database contents including donor and member records.

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 CiviCRM versions up to 6.18.alpha1. It allows authenticated staff users to execute arbitrary SQL queries by exploiting improper input sanitization in the contact search RLIKE clause. The vulnerability enables reading the entire database, including sensitive records like donor and member information.

Detection Guidance

To detect this SQL injection vulnerability in CiviCRM, inspect web server logs for unusual contact search queries containing RLIKE clauses with suspicious input patterns. Look for authenticated staff accounts making repeated or large database queries. Check for unexpected data exfiltration attempts in network traffic.

Impact Analysis

If you are a CiviCRM user with staff-level access, an attacker could exploit this to steal all database contents, including personal and financial data of donors, members, or other contacts. This could lead to data breaches, reputational damage, legal consequences, and financial loss.

Compliance Impact

This vulnerability likely violates GDPR due to unauthorized access to personal data and potential failure to implement adequate security measures. It may also breach HIPAA if protected health information is exposed. Organizations could face heavy fines, mandatory breach notifications, and loss of compliance certifications.

Mitigation Strategies

Immediately update CiviCRM to the latest patched version. If an update is unavailable, disable the contact search RLIKE functionality or restrict staff-level database access. Implement strict input validation for all user-supplied data in SQL queries. Monitor database activity for unauthorized access attempts.
