CVE-2024-45850
📋 TL;DR
This vulnerability allows remote code execution on MindsDB servers when the Microsoft SharePoint integration is installed. Attackers can craft malicious INSERT queries containing Python code that gets executed via eval() on the server. Organizations running MindsDB versions 23.10.5.0 through 24.7.4.1 with SharePoint integration are affected.

⚠️ Risk & Real-World Impact
Worst Case
Full server compromise allowing attackers to execute arbitrary commands, steal data, install malware, pivot to other systems, or disrupt operations.
Likely Case
Unauthorized data access, modification, or deletion in SharePoint-connected databases, with potential for lateral movement within the network.
If Mitigated
Limited impact if proper network segmentation, query validation, and least privilege access controls are implemented.
🎯 Exploit Status
Exploitation requires database access privileges to execute INSERT queries against SharePoint-connected databases.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 24.7.4.2 or later
Vendor Advisory: https://hiddenlayer.com/sai-security-advisory/2024-09-mindsdb/
Restart Required: Yes
Instructions:
1. Backup MindsDB configuration and data. 2. Upgrade to MindsDB version 24.7.4.2 or later. 3. Restart the MindsDB service. 4. Verify the upgrade was successful.
🔧 Temporary Workarounds
Disable SharePoint Integration
allRemove or disable the Microsoft SharePoint integration from MindsDB to eliminate the attack vector.
# Remove SharePoint connector if installed
# Check MindsDB documentation for specific removal commands
Restrict Database Access
allImplement strict access controls to limit who can execute queries against SharePoint-connected databases.
# Configure MindsDB user permissions to restrict INSERT operations
# Use database role-based access control
🧯 If You Can't Patch
- Implement network segmentation to isolate MindsDB servers from critical systems
- Deploy web application firewall (WAF) rules to detect and block malicious INSERT queries
🔍 How to Verify
Check if Vulnerable:
Check MindsDB version and verify if SharePoint integration is installed. Vulnerable if version is between 23.10.5.0 and 24.7.4.1 inclusive.Check Version:
mindsdb --versionVerify Fix Applied:
Confirm MindsDB version is 24.7.4.2 or later and test that eval() execution no longer occurs with crafted INSERT queries.📡 Detection & Monitoring
