CVE-2025-36553

8.8 HIGH

📋 TL;DR

A buffer overflow vulnerability in Dell ControlVault3 and ControlVault3 Plus allows memory corruption via specially crafted API calls. Attackers could potentially execute arbitrary code or cause system crashes. This affects Dell systems running vulnerable versions of ControlVault3 firmware.

💻 Affected Systems

Products:
  • Dell ControlVault3
  • Dell ControlVault3 Plus
Versions: ControlVault3 prior to 5.15.14.19, ControlVault3 Plus prior to 6.2.36.47
Operating Systems: Windows, Linux (on affected Dell systems)
Default Config Vulnerable: ⚠️ Yes
Notes: Affects Dell systems with ControlVault3 hardware security modules. The vulnerability is in the firmware/API layer.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution with SYSTEM/root privileges leading to complete system compromise, credential theft, and lateral movement.

🟠

Likely Case

System instability, crashes, denial of service, or limited code execution depending on exploit sophistication.

🟢

If Mitigated

System crashes or instability without code execution if memory protections are enabled.

🌐 Internet-Facing: MEDIUM - Requires API access which may be exposed in some configurations, but typically requires local network access.
🏢 Internal Only: HIGH - Attackers on the local network or with initial access can exploit this to escalate privileges.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires crafting specific API calls to ControlVault functionality. No public exploits 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 firmware update from Dell Support. 2. Run the firmware update utility. 3. Restart the system. 4. Verify firmware version is updated.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to systems with ControlVault3 to trusted networks only.

API Access Control

all

Implement strict access controls for ControlVault API endpoints if configurable.

🧯 If You Can't Patch

  • Isolate affected systems from untrusted networks and users
  • Implement application allowlisting to prevent unauthorized processes

🔍 How to Verify

Check if Vulnerable:

Check ControlVault firmware version via Dell Command | Update or system BIOS settings.

Check Version:

On Windows: wmic bios get smbiosbiosversion (may show ControlVault info) or check Dell Update utility. On Linux: dmidecode -t bios

Verify Fix Applied:

Verify firmware 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 ControlVault API calls
  • System crashes or reboots
  • Memory access violations in system logs

Network Indicators:

  • Unusual traffic to ControlVault service ports
  • Multiple failed API calls followed by buffer overflow patterns

SIEM Query:

source="system_logs" AND ("ControlVault" OR "CvManager") AND ("access violation" OR "buffer overflow" OR "exception")
