CVE-2019-1000023
📋 TL;DR
This SQL injection vulnerability in OPTOSS NG-NetMS allows attackers to execute arbitrary SQL commands via network-accessible parameters (id, id_access_type, id_attr_access). Organizations running affected versions of this network management system are at risk of database compromise.
💻 Affected Systems
- OPTOSS Next Gen Network Management System (NG-NetMS)
📦 What is this software?
Ng Netms by Opt Net
⚠️ Risk & Real-World Impact
Worst Case
Complete database compromise leading to data theft, system takeover, and lateral movement to other systems
Likely Case
Database information disclosure, data manipulation, and potential privilege escalation
If Mitigated
Limited impact with proper input validation and database permissions in place
🎯 Exploit Status
SQL injection via network parameters makes exploitation straightforward
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
1. Check for updated version from vendor 2. Apply parameterized queries 3. Implement input validation
🔧 Temporary Workarounds
Web Application Firewall (WAF)
allDeploy WAF with SQL injection rules to block malicious requests
Network Segmentation
allRestrict network access to NG-NetMS to authorized users only
🧯 If You Can't Patch
- Implement strict input validation and parameterized queries in application code
- Apply database-level controls: least privilege accounts, stored procedures, and query whitelisting
🔍 How to Verify
Check if Vulnerable:
Test vulnerable parameters (id, id_access_type, id_attr_access) with SQL injection payloadsCheck Version:
Check NG-NetMS version in system interface or configuration filesVerify Fix Applied:
Verify parameterized queries are implemented and input validation prevents SQL injection📡 Detection & Monitoring
Log Indicators:
- Unusual SQL queries in database logs
- Multiple failed login attempts
- Suspicious parameter values in web logs
Network Indicators:
- SQL keywords in HTTP parameters
- Unusual database connection patterns
SIEM Query:
source="web_logs" AND (param="id" OR param="id_access_type" OR param="id_attr_access") AND (query="UNION" OR query="SELECT" OR query="INSERT" OR query="DELETE")🔗 References
