CVE-2024-57621
📋 TL;DR
This vulnerability in MonetDB Server's GDKanalytical_correlation component allows attackers to execute crafted SQL statements that cause a Denial of Service (DoS). It affects organizations running vulnerable versions of MonetDB Server, potentially disrupting database operations. The issue stems from SQL injection (CWE-89) in a specific analytical function.

Monetdb by Monetdb
⚠️ Risk & Real-World Impact
Worst Case
Complete database unavailability through resource exhaustion or crash, disrupting all dependent applications and services.
Likely Case
Temporary service degradation or database restart required, causing application downtime until recovery.
If Mitigated
Minimal impact with proper input validation and monitoring; potential performance degradation but no complete outage.
🎯 Exploit Status
Requires ability to execute SQL statements; likely needs database access credentials or SQL injection vector.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for fixed version; likely v11.47.12 or later
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7414
Restart Required: No
Instructions:
1. Check current version with 'monetdb version'. 2. Update to patched version via package manager or source. 3. Verify fix with test queries.
🔧 Temporary Workarounds
Disable vulnerable component
allRestrict or disable usage of GDKanalytical_correlation function if not required
ALTER DATABASE SET 'gdk_analytical_correlation_enabled' = 'false';
Input validation
allImplement strict input validation on SQL queries to block crafted statements
-- Use parameterized queries in applications
🧯 If You Can't Patch
- Implement network segmentation to restrict database access to trusted sources only
- Deploy WAF or database firewall to block suspicious SQL patterns
🔍 How to Verify
Check if Vulnerable:
Test with crafted SQL using GDKanalytical_correlation; monitor for crashes or high resource usage.Check Version:
monetdb versionVerify Fix Applied:
After update, retest with same crafted SQL; system should handle gracefully without DoS.📡 Detection & Monitoring
