CVE-2023-46575
📋 TL;DR
A SQL injection vulnerability in Meshery allows remote attackers to execute arbitrary SQL commands through the 'order' parameter, potentially leading to data theft and remote code execution. This affects all Meshery deployments running versions prior to v0.6.179.
💻 Affected Systems
- Meshery
📦 What is this software?
Meshery by Layer5
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the Meshery database, exfiltration of sensitive configuration data, and remote code execution on the underlying server.
Likely Case
Unauthorized access to sensitive Meshery configuration data, performance metrics, and service mesh management information.
If Mitigated
Limited impact with proper input validation and database permissions, potentially only error messages or partial data exposure.
🎯 Exploit Status
SQL injection through the 'order' parameter is typically straightforward to exploit with common SQL injection techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v0.6.179
Vendor Advisory: https://github.com/meshery/meshery/commit/ffe00967acfe4444a5db08ff3a4cafb9adf6013f
Restart Required: Yes
Instructions:
1. Stop Meshery service. 2. Update to Meshery v0.6.179 or later. 3. Restart Meshery service. 4. Verify the fix by checking the version and testing the vulnerable endpoint.
🔧 Temporary Workarounds
Input Validation Filter
allAdd input validation to sanitize the 'order' parameter before processing
Not applicable - requires code modification
Web Application Firewall
allDeploy WAF with SQL injection protection rules
Depends on specific WAF solution
🧯 If You Can't Patch
- Restrict network access to Meshery endpoints to trusted IPs only
- Implement database user with minimal required permissions
🔍 How to Verify
Check if Vulnerable:
Check if Meshery version is below v0.6.179 and test the 'order' parameter with SQL injection payloadsCheck Version:
mesheryctl versionVerify Fix Applied:
Confirm version is v0.6.179 or later and test that SQL injection attempts are properly rejected📡 Detection & Monitoring
Log Indicators:
