📋 TL;DR
This SQL injection vulnerability in Human Resource Management System version 1.0 allows attackers to manipulate database queries through the 'city' and 'state' parameters, potentially enabling full database access including retrieval, creation, modification, and deletion of data. Organizations using this specific HR software version are affected.
💻 Affected Systems
- Human Resource Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including sensitive HR data exfiltration, credential theft, system takeover, and data destruction
Likely Case
Unauthorized access to employee records, personal data theft, and potential privilege escalation
If Mitigated
Limited impact with proper input validation and database permissions restricting damage to non-sensitive data
🎯 Exploit Status
SQL injection via URL parameters typically requires minimal technical skill
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-human-resource-management-system
Restart Required: No
Instructions:
No official patch available. Consider migrating to alternative HR software or implementing workarounds.
🔧 Temporary Workarounds
Web Application Firewall (WAF) Rules
allImplement WAF rules to block SQL injection patterns in city and state parameters
WAF-specific configuration required
Input Validation Filter
allAdd server-side input validation to restrict city and state parameters to expected formats
Implementation depends on programming language and framework
🧯 If You Can't Patch
- Isolate the HR system in a separate network segment with strict access controls
- Implement database-level permissions to restrict application user to read-only operations
🔍 How to Verify
Check if Vulnerable:
Test /controller/ccity.php endpoint with SQL injection payloads in city or state parametersCheck Version:
Check application version in admin panel or configuration filesVerify Fix Applied:
Verify input validation prevents SQL injection payloads and parameterized queries are implemented📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts following SQL injection patterns
- Unexpected database schema changes
Network Indicators:
- HTTP requests to /controller/ccity.php with SQL keywords in parameters
- Unusual database traffic from web server
SIEM Query:
web.url:*ccity.php* AND (web.param:*UNION* OR web.param:*SELECT* OR web.param:*INSERT* OR web.param:*DELETE*)
