An unauthenticated SQL injection vulnerability in the Fabrik extension for Joomla exposes the database to unauthorized access and potential data exfiltration.

This is an improper neutralization of special elements used in an SQL command (CWE-89). The vulnerability exists because the order parameter in list models is processed without adequate validation, enabling unauthenticated remote attackers to perform SQL injection attacks.

Successful exploitation allows an attacker to manipulate database queries, potentially leading to the full compromise of sensitive application data. With a CVSS score of 9.3, this critical vulnerability poses a severe risk to data confidentiality and integrity, which could result in significant regulatory non-compliance and reputational damage.

Immediate Action: Update the Fabrik extension for Joomla to a version beyond 4.7.3 immediately.

Proactive Monitoring: Monitor database query logs for unusual syntax, such as unexpected ORDER BY clauses or patterns indicative of SQL injection attempts.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block SQL injection payloads targeting Joomla extensions.

Public Exploit Available: Unknown

Due to the critical severity and the ease of exploitation, organizations using the Fabrik extension must prioritize this update. Immediate patching is the only effective way to prevent unauthorized database access and secure the application environment.
