CVE-2024-57650
📋 TL;DR
This vulnerability in OpenLink Virtuoso Open-Source Edition allows attackers to cause Denial of Service (DoS) by sending specially crafted SQL statements. The issue resides in the qi_inst_state_free component and affects systems running vulnerable versions of the database software. Attackers with network access to the database server can exploit this vulnerability.
💻 Affected Systems
- OpenLink Virtuoso Open-Source Edition
📦 What is this software?
Virtuoso by Openlinksw
⚠️ Risk & Real-World Impact
Worst Case
Complete database service disruption, making the database unavailable for all applications and users, potentially requiring service restart or system reboot.
Likely Case
Database service crashes or becomes unresponsive, affecting dependent applications until manual intervention restores service.
If Mitigated
Minimal impact with proper network segmentation and access controls limiting who can send SQL queries to the database.
🎯 Exploit Status
Requires ability to send SQL statements to the database. The CWE-89 (SQL Injection) classification suggests the vulnerability involves improper handling of SQL input.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for latest patched version
Vendor Advisory: https://github.com/openlink/virtuoso-opensource/issues/1204
Restart Required: No
Instructions:
1. Monitor the GitHub issue for patch release. 2. Upgrade to the patched version when available. 3. Test the upgrade in a non-production environment first.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the database server to only trusted applications and users.
Use firewall rules to limit database port access (typically 1111, 8890 for Virtuoso)
Input Validation
allImplement application-level validation of SQL queries before sending to database.
Implement parameterized queries and input sanitization in applications
🧯 If You Can't Patch
- Implement strict network segmentation to isolate database servers
- Deploy Web Application Firewall (WAF) with SQL injection protection rules
🔍 How to Verify
Check if Vulnerable:
Check Virtuoso version: vsql -V or check server logs for version informationCheck Version:
vsql -V 2>&1 | grep VersionVerify Fix Applied:
After patching, verify the version is updated and test with normal SQL operations📡 Detection & Monitoring
