CVE-2022-22557
📋 TL;DR
Dell PowerStore storage systems store certain user credentials in plain text, allowing locally authenticated attackers to read sensitive passwords. This affects PowerStore X & T environments running vulnerable versions, potentially enabling attackers to gain unauthorized access with compromised account privileges.
💻 Affected Systems
- Dell PowerStore X
- Dell PowerStore T
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain administrative access to PowerStore management interface, potentially compromising the entire storage infrastructure and accessing sensitive data.
Likely Case
Attackers obtain credentials for standard user accounts, allowing unauthorized access to storage management functions and potentially sensitive data.
If Mitigated
With proper network segmentation and access controls, impact is limited to the local system with minimal lateral movement potential.
🎯 Exploit Status
Exploitation requires local access to the system. The vulnerability involves reading plain-text credentials from storage locations.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.1.0.0 or later
Vendor Advisory: https://www.dell.com/support/kbdoc/000196367
Restart Required: Yes
Instructions:

🔧 Temporary Workarounds
Restrict Local Access
allLimit physical and logical access to PowerStore systems to authorized personnel only.
Network Segmentation
allIsolate PowerStore management interfaces from general network access.
🧯 If You Can't Patch
- Implement strict access controls to limit who can authenticate locally to PowerStore systems
- Monitor authentication logs for suspicious access patterns and credential usage
🔍 How to Verify
Check if Vulnerable:
Check PowerStore version in PowerStore Manager under System > Software. If version is 2.0.0.x or 2.0.1.x, system is vulnerable.Check Version:
In PowerStore Manager: System > Software > Version InformationVerify Fix Applied:
Verify PowerStore version is 2.1.0.0 or later in PowerStore Manager. Check that credential storage mechanisms no longer contain plain-text passwords.📡 Detection & Monitoring
