🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-sergestec-products
Restart Required: No
Instructions:
1. Monitor vendor for patch release. 2. Apply patch when available. 3. Test in non-production environment first. 4. Deploy to production systems.
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation for the 'cat' parameter to only allow expected values
# Example PHP validation
$cat = $_GET['cat'];
if (!preg_match('/^[a-zA-Z0-9_]+$/', $cat)) {
die('Invalid input');
}
Web Application Firewall Rules
allDeploy WAF rules to block SQL injection patterns in the 'cat' parameter
# Example ModSecurity rule
SecRule ARGS:cat "@detectSQLi" "id:1001,phase:2,deny,status:403"
🧯 If You Can't Patch
- Implement network segmentation to isolate Exito systems from sensitive networks
- Deploy database monitoring to detect unusual SQL queries and access patterns
🔍 How to Verify
Check if Vulnerable:
Test the '/public.php' endpoint with SQL injection payloads in the 'cat' parameter (e.g., cat=1' OR '1'='1)
Check Version:
Check Exito version in application interface or configuration files
Verify Fix Applied:
Retest with SQL injection payloads after applying fixes; successful payloads should be rejected or sanitized
📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts or parameter manipulation in web logs
- Database schema changes or unusual table access
Network Indicators:
- SQL injection patterns in HTTP requests to '/public.php'
- Unusual database connection patterns from web servers
SIEM Query:
source="web_logs" AND uri="/public.php" AND (param="cat" AND value MATCHES "[';]|OR|UNION|SELECT")
