CVE-2024-57617
📋 TL;DR
This vulnerability in MonetDB Server's dameraulevenshtein 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 and potentially earlier versions. Organizations running vulnerable MonetDB instances 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 service outage requiring server restart, potentially causing extended downtime and data unavailability.
Likely Case
Temporary service disruption affecting database operations until the server is restarted.
If Mitigated
Minimal impact with proper input validation and monitoring in place to detect and block malicious queries.
🎯 Exploit Status
Requires ability to execute SQL statements against the database, typically through application access or database credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for latest patched version
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7432
Restart Required: No
Instructions:
1. Check the GitHub issue for the latest patched version. 2. Upgrade MonetDB Server to the patched version. 3. Test the upgrade in a non-production environment first.
🔧 Temporary Workarounds
Disable dameraulevenshtein component
allTemporarily disable or restrict access to the vulnerable dameraulevenshtein functionality
-- Configuration depends on MonetDB setup and usage patterns
Implement SQL input validation
allAdd application-level validation to filter or sanitize SQL queries before execution
-- Implementation specific to application framework
🧯 If You Can't Patch
- Implement network segmentation to restrict database access to trusted sources only
- Deploy web application firewall (WAF) with SQL injection protection rules
- Monitor database logs for unusual SQL patterns and implement rate limiting
🔍 How to Verify
Check if Vulnerable:
Check MonetDB version: if running v11.49.1 or earlier, assume vulnerable. Test with controlled SQL queries using dameraulevenshtein functions.Check Version:
SELECT monetdb_version();Verify Fix Applied:
After patching, verify version is updated and test that previously crashing SQL queries no longer cause DoS.📡 Detection & Monitoring
Log Indicators:
- Database crash logs
- Unusual dameraulevenshtein function calls
- SQL query patterns causing high resource usage
Network Indicators:
- Sudden drop in database connectivity
- Increased error responses from database layer
SIEM Query:
source="monetdb.log" AND ("crash" OR "segfault" OR "dameraulevenshtein")
