CVE-2024-53292
📋 TL;DR
Dell VxVerify versions before x.40.405 store passwords in plain text within shell wrapper files. A local high-privileged attacker can read these credentials and use them to access the vulnerable component with the compromised account's privileges. This affects Dell VxRail systems running vulnerable VxVerify versions.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker with local high privileges obtains administrative credentials, leading to full system compromise, lateral movement, and potential data exfiltration.
Likely Case
A malicious insider or compromised high-privilege account reads stored passwords and gains unauthorized access to VxVerify components.
If Mitigated
With proper access controls and monitoring, exploitation is limited to credential exposure without successful lateral movement.
🎯 Exploit Status
Exploitation involves reading plain-text password files, which is trivial for attackers with required privileges. No authentication bypass needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: x.40.405 or later
Vendor Advisory: https://www.dell.com/support/kbdoc/en-us/000258964/dsa-2024-492-security-update-dell-vxverify-on-vxrail-plaintext-password-storage-vulnerabilities
Restart Required: Yes
Instructions:
1. Download the patch from Dell Support. 2. Apply the update to VxVerify. 3. Restart affected services or systems as required.
🔧 Temporary Workarounds
Restrict shell wrapper file access
linuxLimit read permissions on shell wrapper files containing passwords to only necessary users.
chmod 600 /path/to/wrapper/files
chown root:root /path/to/wrapper/files
🧯 If You Can't Patch
- Implement strict access controls to limit local high-privilege accounts and monitor for suspicious file access.
- Rotate all credentials stored by VxVerify and ensure they are not reused elsewhere.
🔍 How to Verify
Check if Vulnerable:
Check VxVerify version using 'vxverify --version' or similar command and compare to x.40.405.Check Version:
vxverify --versionVerify Fix Applied:
Verify version is x.40.405 or later and check that shell wrapper files no longer contain plain-text passwords.📡 Detection & Monitoring
Log Indicators:
- Unusual access to shell wrapper files by non-administrative users
- Failed authentication attempts followed by successful logins with previously stored credentials
Network Indicators:
- Unexpected network connections from VxVerify systems to sensitive internal resources
SIEM Query:
