CVE-2024-57629
📋 TL;DR
This vulnerability in MonetDB Server's tail_type component allows attackers to execute crafted SQL statements that cause a Denial of Service (DoS) by crashing or hanging the database server. It affects MonetDB Server version 11.49.1 specifically. Database administrators running this version are at risk of service disruption.
💻 Affected Systems
- MonetDB Server
📦 What is this software?
Monetdb by Monetdb
⚠️ Risk & Real-World Impact
Worst Case
Complete database server crash requiring manual restart, leading to extended service downtime and potential data corruption.
Likely Case
Temporary service disruption where the database becomes unresponsive, requiring restart and causing brief application downtime.
If Mitigated
Minimal impact with proper network segmentation and SQL input validation preventing malicious queries from reaching the database.
🎯 Exploit Status
Exploitation requires knowledge of SQL injection techniques specific to MonetDB's tail_type component. No authentication bypass is needed as SQL execution is typically allowed to database users.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 11.49.1 (check GitHub issue for specific fixed version)
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7472
Restart Required: No
Instructions:
1. Check the GitHub issue for the specific fixed version. 2. Upgrade MonetDB Server to the patched version. 3. No database restart is required for the patch itself, but restart may be needed if currently experiencing DoS.
🔧 Temporary Workarounds
SQL Input Validation
allImplement strict input validation on all SQL queries to prevent crafted statements from reaching the database.
Network Access Restrictions
allRestrict database access to only trusted application servers using firewall rules.
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) with SQL injection protection rules
- Monitor database logs for unusual SQL patterns and implement rate limiting on database connections
🔍 How to Verify
Check if Vulnerable:
Check MonetDB version with 'monetdb version' command. If version is exactly 11.49.1, the system is vulnerable.
Check Version:
monetdb version
Verify Fix Applied:
After upgrade, verify version is no longer 11.49.1. Test with normal SQL operations to ensure functionality.
