CVE-2025-3799 Overview
A critical SQL injection vulnerability has been identified in WCMS 11, specifically affecting the AnonymousController.php file within the application's controllers directory. The vulnerability allows remote attackers to manipulate the email and username parameters to inject malicious SQL queries, potentially compromising the underlying database and sensitive user data.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability without authentication to extract sensitive data, modify database contents, or potentially gain unauthorized access to the WCMS application.
Affected Products
- WCMS version 11.0
- Applications using app/controllers/AnonymousController.php
- Systems with exposed WCMS login or registration endpoints

Technical Details for CVE-2025-3799
Vulnerability Analysis
This SQL injection vulnerability exists in the AnonymousController.php file of WCMS 11. The vulnerable code fails to properly sanitize user-supplied input in the email and username parameters before incorporating them into SQL queries. This allows attackers to inject arbitrary SQL commands that execute with the privileges of the database user configured for the WCMS application.
The vulnerability is remotely exploitable with no authentication required, making it accessible to any attacker with network access to the affected system. The advisory notes that other parameters in the same controller may also be affected by similar injection issues.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the AnonymousController.php file. The application directly incorporates user-controlled data from the email and username fields into database queries without proper sanitization or the use of prepared statements, violating secure coding practices for database interaction.
Attack Vector
The attack is conducted remotely over the network by sending crafted HTTP requests to endpoints handled by the AnonymousController.php controller. Attackers manipulate the email or username parameters with SQL injection payloads to extract data, bypass authentication, or modify database contents. Since the attack requires no prior authentication, any anonymous user with network access to the WCMS application can attempt exploitation.
The vulnerability has been publicly disclosed, and technical details are available through the GitHub Issue #15 security report, increasing the risk of exploitation in the wild.
Detection Methods for CVE-2025-3799
Indicators of Compromise
- Unusual SQL error messages in application logs containing injection syntax
- Authentication bypass attempts targeting the WCMS login functionality
- Database query logs showing unexpected UNION SELECT, OR 1=1, or other SQL injection patterns
- Anomalous access patterns to AnonymousController.php endpoints
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns in the email and username parameters
- Enable detailed logging for the WCMS application and monitor for SQL syntax errors or unusual database queries
- Implement intrusion detection system (IDS) signatures for SQL injection attempts targeting WCMS endpoints
- Review web server access logs for suspicious requests containing encoded SQL commands
Monitoring Recommendations
- Monitor database query logs for unauthorized data extraction or modification attempts
- Set up alerts for failed authentication attempts that may indicate injection-based bypass attempts
- Track access frequency to AnonymousController.php endpoints for anomaly detection
- Implement real-time security monitoring for web application traffic patterns
How to Mitigate CVE-2025-3799
Immediate Actions Required
- Restrict network access to the WCMS application to trusted networks only until a patch is available
- Implement input validation at the web server or WAF level to filter SQL injection payloads
- Review and sanitize all user inputs in AnonymousController.php using parameterized queries
- Consider temporarily disabling anonymous registration or login functionality if not business-critical
Patch Information
At the time of this writing, no official patch information has been released by the WCMS vendor. Organizations should monitor the VulDB entry and vendor channels for updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.
Workarounds
- Deploy a Web Application Firewall (WAF) with SQL injection detection rules as a compensating control
- Modify app/controllers/AnonymousController.php to use prepared statements and parameterized queries for all database operations involving user input
- Implement server-side input validation to reject input containing SQL metacharacters in the email and username fields
- Restrict database user privileges to the minimum required for application functionality
# Example WAF rule for ModSecurity to block SQL injection attempts
SecRule ARGS:email|ARGS:username "@detectSQLi" \
"id:100001,phase:2,deny,status:403,msg:'SQL Injection attempt detected in WCMS parameters'"
