CVE-2024-57628
📋 TL;DR
This vulnerability in MonetDB Server allows attackers to execute crafted SQL statements that trigger a denial of service condition in the exp_values_set_supertype component. Systems running vulnerable versions of MonetDB Server are affected, potentially disrupting database availability.
💻 Affected Systems
- MonetDB Server
📦 What is this software?
Monetdb by Monetdb
⚠️ Risk & Real-World Impact
Worst Case
Complete database service disruption, making the MonetDB instance unavailable for all applications and users.
Likely Case
Temporary service interruption requiring database restart, causing application downtime and data processing delays.
If Mitigated
Minimal impact with proper network segmentation and access controls limiting who can execute SQL against the database.
🎯 Exploit Status
Requires ability to execute SQL statements against the MonetDB Server. The CWE-89 classification suggests SQL injection techniques may be involved.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for patched version
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7437
Restart Required: No
Instructions:
1. Check the GitHub issue for patch availability. 2. Update MonetDB Server to the patched version. 3. Test the update in a non-production environment first.
🔧 Temporary Workarounds
Restrict SQL Execution
allLimit which users and applications can execute SQL statements against the MonetDB Server
Network Access Controls
linuxImplement firewall rules to restrict access to MonetDB Server ports (default 50000)
iptables -A INPUT -p tcp --dport 50000 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 50000 -j DROP
🧯 If You Can't Patch
- Implement strict input validation for all SQL queries
- Deploy network segmentation to isolate MonetDB Server from untrusted networks
🔍 How to Verify
Check if Vulnerable:
Check MonetDB Server version and compare against vulnerable versions. Monitor for unexpected service crashes.Check Version:
mclient --version or check MonetDB server logs for version informationVerify Fix Applied:
After patching, attempt to reproduce the issue with test SQL statements and verify service stability.📡 Detection & Monitoring
