CVE-2025-21102
📋 TL;DR
Dell VxRail versions 7.0.000 through 7.0.532 store passwords in plaintext, allowing a high-privileged attacker with local access to read sensitive credentials. This vulnerability leads to information exposure, potentially compromising system security. Only users of affected VxRail versions are impacted.
💻 Affected Systems
- Dell VxRail
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker gains access to administrative passwords, leading to full system compromise, data theft, or lateral movement within the network.
Likely Case
A malicious insider or compromised high-privileged account reads stored passwords, exposing credentials for further exploitation.
If Mitigated
With strict access controls and monitoring, impact is limited to credential exposure without successful misuse.
🎯 Exploit Status
Exploitation requires high-privileged local access; no public exploits known as of the advisory.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to a version beyond 7.0.532 as per Dell advisory
Restart Required: No
Instructions:
1. Review Dell advisory DSA-2025-027. 2. Apply the recommended update to VxRail version beyond 7.0.532. 3. Follow Dell's update procedures for VxRail systems.
🔧 Temporary Workarounds
Restrict Local Access
allLimit high-privileged local access to essential personnel only to reduce attack surface.
🧯 If You Can't Patch
- Implement strict access controls and monitoring for high-privileged accounts to detect suspicious activities.
- Regularly audit and rotate stored passwords to minimize impact if exposed.
🔍 How to Verify
Check if Vulnerable:
Check VxRail version via management interface or CLI; if between 7.0.000 and 7.0.532, it is vulnerable.Check Version:
Use VxRail management tools or CLI commands specific to the system (e.g., 'vxrail version' or similar as per Dell documentation).Verify Fix Applied:
Confirm VxRail version is updated beyond 7.0.532 using the version check command.📡 Detection & Monitoring
Log Indicators:
- Unusual access to password storage files or directories by high-privileged users
Network Indicators:
- None, as exploitation is local
SIEM Query:
Search for log events indicating file access to sensitive storage locations by privileged accounts on VxRail systems.
