CVE-2025-31649
📋 TL;DR
A hard-coded password vulnerability in Dell ControlVault3 and ControlVault3 Plus drivers allows attackers to execute privileged operations via specially crafted API calls. This affects Dell systems with ControlVault3 prior to 5.15.14.19 or ControlVault3 Plus prior to 6.2.36.47. Attackers can leverage this to bypass authentication and perform unauthorized actions.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code with highest privileges, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Privilege escalation allowing attackers to bypass security controls, access sensitive data, or modify system configurations.
If Mitigated
Limited impact if systems are isolated, have strict network controls, and attackers cannot reach the vulnerable API endpoints.
🎯 Exploit Status
Exploitation requires crafting specific API calls but is straightforward once the hard-coded credentials are known. No public exploit code available as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: ControlVault3 5.15.14.19 or later, ControlVault3 Plus 6.2.36.47 or later
Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000326061/dsa-2025-228
Restart Required: Yes
Instructions:
1. Download the updated driver from Dell Support. 2. Run the installer with administrative privileges. 3. Restart the system when prompted. 4. Verify the driver version after reboot.
🔧 Temporary Workarounds
Disable ControlVault WBDI Driver
windowsTemporarily disable the vulnerable driver functionality if patching is not immediately possible.
sc stop ControlVaultWBDI
sc config ControlVaultWBDI start= disabled
Network Segmentation
allRestrict network access to systems with ControlVault to prevent remote exploitation.
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems from untrusted networks.
- Deploy application allowlisting to prevent execution of unauthorized processes on vulnerable systems.
🔍 How to Verify
Check if Vulnerable:
Check ControlVault driver version in Device Manager (Windows) or via 'modinfo' command (Linux). Compare against vulnerable versions.Check Version:

Verify driver version is 5.15.14.19 or later for ControlVault3, or 6.2.36.47 or later for ControlVault3 Plus.📡 Detection & Monitoring
Log Indicators:
- Unusual API calls to ControlVault services
- Failed authentication attempts followed by successful privileged operations
- Unexpected process execution with high privileges
Network Indicators:
- Unusual network traffic to ControlVault API endpoints (typically local/127.0.0.1)
- Suspicious RPC calls to ControlVault services
