CVE-2025-6807
📋 TL;DR
This vulnerability allows remote attackers to read sensitive files on Marvell QConvergeConsole installations without authentication. Attackers can exploit a directory traversal flaw in the getDriverTmpPath method to access arbitrary files with SYSTEM privileges. All affected installations are vulnerable to information disclosure.
💻 Affected Systems
- Marvell QConvergeConsole
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through disclosure of credentials, configuration files, or other sensitive data leading to lateral movement or privilege escalation.
Likely Case
Disclosure of sensitive system information, configuration files, or application data that could facilitate further attacks.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external access to vulnerable systems.
🎯 Exploit Status
Directory traversal vulnerabilities are typically easy to exploit with simple HTTP requests
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Marvell advisory for specific patched version
Vendor Advisory: https://www.marvell.com/support/security-advisories.html
Restart Required: Yes
Instructions:
1. Check Marvell security advisory for affected versions. 2. Download and apply the latest patch from Marvell support portal. 3. Restart the QConvergeConsole service. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to QConvergeConsole to trusted IP addresses only
Use firewall rules to limit access to specific source IPs
Authentication Enforcement
allImplement additional authentication layer if possible
Configure web server authentication or implement reverse proxy with authentication
🧯 If You Can't Patch
- Isolate vulnerable systems in separate network segments with strict access controls
- Implement web application firewall (WAF) rules to block directory traversal patterns
🔍 How to Verify
Check if Vulnerable:
Test for directory traversal by attempting to access files outside the intended directory via the vulnerable endpointCheck Version:
Check QConvergeConsole version in web interface or configuration filesVerify Fix Applied:
Attempt the same directory traversal test after patching; successful patch should return proper error instead of file contents📡 Detection & Monitoring
Log Indicators:
- HTTP requests containing '../' patterns
- Unusual file access patterns from external IPs
- Failed authentication attempts followed by file access
Network Indicators:
- HTTP requests with path traversal sequences to QConvergeConsole endpoints
- Unusual outbound data transfers following traversal attempts
SIEM Query:
source="web_logs" AND (url="*../*" OR url="*..\\*" OR url="*%2e%2e%2f*") AND dest_ip="[QConvergeConsole_IP]"
