Queue Ticket Kiosk by Realcetecnologia
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to steal all database contents, execute arbitrary commands, and potentially pivot to other systems in the network.
Likely Case
Authentication bypass leading to unauthorized admin access, data exfiltration of sensitive queue/ticket information, and potential manipulation of kiosk operations.
If Mitigated
Limited impact with proper network segmentation, WAF protection, and database permissions restricting damage to the kiosk application only.
🎯 Exploit Status
SQL injection vulnerabilities are commonly weaponized. The vulnerability is in the login page, making it accessible without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None available
Restart Required: No
Instructions:
No official patch available. Contact vendor for updates or consider alternative solutions.
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy a WAF with SQL injection protection rules to block exploitation attempts
Network Segmentation
linuxRestrict access to the admin interface to trusted IP addresses only
iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT
iptables -A INPUT -p tcp --dport [PORT] -j DROP
🧯 If You Can't Patch
- Isolate the kiosk system on a separate network segment with no access to sensitive systems
- Implement strict input validation and parameterized queries if source code modification is possible
🔍 How to Verify
Check if Vulnerable:
Check if /adm/index.php exists and accepts user input in the login form. Test with SQL injection payloads like ' OR '1'='1Check Version:
Check software version in admin panel or configuration filesVerify Fix Applied:
Verify that SQL injection payloads no longer work and that input is properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual SQL syntax in login attempts
- Multiple failed login attempts with SQL keywords
- Admin access from unexpected IP addresses
Network Indicators:
- HTTP requests to /adm/index.php containing SQL keywords like UNION, SELECT, OR
SIEM Query:
source="web_logs" AND uri="/adm/index.php" AND (request CONTAINS "UNION" OR request CONTAINS "SELECT" OR request CONTAINS "OR '1'='1'")
