CVE-2024-57619
📋 TL;DR
This vulnerability in MonetDB Server's atom_get_int component allows attackers to execute crafted SQL statements that cause a Denial of Service (DoS) by crashing or hanging the database server. It affects all systems running vulnerable versions of MonetDB Server, particularly those exposed to untrusted SQL input. Database administrators and applications using MonetDB are impacted.
💻 Affected Systems
- MonetDB Server
📦 What is this software?
Monetdb by Monetdb
⚠️ Risk & Real-World Impact
Worst Case
Complete database service disruption requiring restart, potential data corruption if transactions are interrupted, and extended downtime affecting dependent applications.
Likely Case
Temporary database unavailability requiring manual restart, moderate service disruption affecting users and applications.
If Mitigated
Minimal impact with proper input validation and monitoring allowing quick detection and recovery.
🎯 Exploit Status
Requires ability to execute SQL statements against the database. Attackers need database access credentials or SQL injection vectors.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for latest patched version
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7416
Restart Required: No
Instructions:
1. Check current MonetDB version. 2. Update to latest patched version from official MonetDB repository. 3. Verify fix by testing with known problematic SQL patterns.
🔧 Temporary Workarounds
Input Validation and Filtering
allImplement strict input validation for SQL statements, particularly for integer parsing operations
-- Application-level: Validate all user inputs before passing to MonetDB
-- Database-level: Use prepared statements with parameterized queries
Access Control Restrictions
allLimit database access to trusted applications and users only
-- MonetDB SQL: REVOKE EXECUTE ON ALL FUNCTIONS FROM PUBLIC
-- Network: Restrict database port access to application servers only
🧯 If You Can't Patch
- Implement network segmentation to isolate MonetDB servers from untrusted networks
- Deploy Web Application Firewall (WAF) or database firewall to filter malicious SQL patterns
🔍 How to Verify
Check if Vulnerable:
Check if running MonetDB Server version 11.47.11 or earlier. Test with controlled SQL statements that trigger integer parsing errors.
Check Version:
monetdbd get version or check monetdb --version
Verify Fix Applied:
After patching, attempt to reproduce the DoS with crafted SQL statements that previously caused issues. Monitor for service stability.
📡 Detection & Monitoring
Log Indicators:
- Database crash logs
- Unexpected service restarts
- SQL error messages related to integer parsing
- High CPU/memory usage before crash
Network Indicators:
- Unusual SQL query patterns targeting integer functions
- Multiple failed connection attempts after DoS
SIEM Query:
source="monetdb.log" AND ("crash" OR "segmentation fault" OR "atom_get_int" OR "unexpected shutdown")
