⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise including data theft, data manipulation, privilege escalation, and potential remote code execution through database functions.
Likely Case
Unauthorized data access, data exfiltration, and potential privilege escalation within the application.
If Mitigated
Limited impact with proper input validation, parameterized queries, and least privilege database accounts.
🎯 Exploit Status
Exploitation requires authentication but can be combined with CSRF attacks
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.7.3 or later
Vendor Advisory: https://www.rukovoditel.net/
Restart Required: No
Instructions:
1. Backup your database and application files. 2. Download the latest version from the official website. 3. Replace the vulnerable files with patched versions. 4. Verify the entities/fields page functionality.
🔧 Temporary Workarounds
Input Validation Filter
allAdd server-side validation for entities_id parameter to accept only numeric values
Modify application code to validate entities_id parameter as integer before processing
WAF Rule
allImplement web application firewall rules to block SQL injection patterns
Add WAF rule: Detect and block SQL injection patterns in entities_id parameter
🧯 If You Can't Patch
- Implement strict input validation for entities_id parameter to only accept numeric values
- Apply principle of least privilege to database accounts used by the application
🔍 How to Verify
Check if Vulnerable:
Check if running version 2.7.2 and test entities/fields page with SQL injection payloads in entities_id parameterCheck Version:
Check application version in admin panel or read version.txt fileVerify Fix Applied:
Verify version is 2.7.3 or later and test that SQL injection payloads no longer work📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts followed by entities/fields access
- CSRF token mismatches
Network Indicators:
- HTTP POST requests to entities/fields with SQL injection patterns in parameters
SIEM Query:
source="web_logs" AND (uri="/entities/fields" AND (param="entities_id" AND value MATCH "[';]|UNION|SELECT"))
