CVE-2024-57625
📋 TL;DR
This vulnerability in MonetDB Server allows attackers to execute crafted SQL statements that trigger a denial of service condition in the merge_table_prune_and_unionize component. The vulnerability affects MonetDB Server installations, potentially disrupting database availability. Attackers with SQL execution privileges can exploit this flaw.
💻 Affected Systems
- MonetDB Server
📦 What is this software?
Monetdb by Monetdb
⚠️ Risk & Real-World Impact
Worst Case
Complete database service disruption requiring restart, potentially affecting all applications relying on the MonetDB instance.
Likely Case
Temporary service interruption affecting database availability until the service is restarted.
If Mitigated
Minimal impact if proper network segmentation and access controls prevent unauthorized SQL execution.
🎯 Exploit Status
Requires SQL execution capability; exploitation involves crafting specific SQL statements targeting the vulnerable component.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for specific patched version
Vendor Advisory: https://github.com/MonetDB/MonetDB/issues/7443
Restart Required: No
Instructions:
1. Check the GitHub issue for patched version information. 2. Upgrade MonetDB Server to the patched version. 3. Verify the fix by testing with previously problematic SQL statements.
🔧 Temporary Workarounds
SQL Input Validation
allImplement strict input validation and parameterized queries to prevent malicious SQL statements from reaching the vulnerable component.
Access Control Restriction
allRestrict SQL execution privileges to trusted users and applications only.
🧯 If You Can't Patch
- Implement network segmentation to isolate MonetDB instances from untrusted networks
- Deploy web application firewall (WAF) rules to detect and block suspicious SQL patterns
🔍 How to Verify
Check if Vulnerable:
Check MonetDB Server version; if running v11.49.1, the system is vulnerable.Check Version:
SELECT version FROM sys.version;Verify Fix Applied:
After patching, attempt to reproduce the issue with test SQL statements; service should remain stable.📡 Detection & Monitoring
