CVE-2026-22267
📋 TL;DR
Dell PowerProtect Data Manager versions before 19.22 have an incorrect privilege assignment vulnerability that allows low-privileged remote attackers to elevate their privileges. This affects organizations using vulnerable versions of Dell's data protection software for backup and recovery operations.
💻 Affected Systems
- Dell PowerProtect Data Manager
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker gains administrative control over the PowerProtect Data Manager, potentially compromising all backup data, disrupting recovery operations, and using the system as a foothold to attack other connected systems.
Likely Case
An authenticated low-privileged user escalates to administrative privileges, gaining unauthorized access to sensitive backup data and system configuration.
If Mitigated
With proper network segmentation and access controls, exploitation is limited to authorized users only, reducing the attack surface.
🎯 Exploit Status
Requires authenticated low-privileged access, but privilege escalation mechanisms are typically straightforward once initial access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 19.22 or later

Review PowerProtect user accounts and remove unnecessary accounts
Implement role-based access controls with minimal required permissions
🧯 If You Can't Patch
- Isolate PowerProtect Data Manager on a dedicated management network segment with strict access controls
- Implement comprehensive logging and monitoring for privilege escalation attempts and unusual administrative activity
🔍 How to Verify
Check if Vulnerable:
Check the PowerProtect Data Manager version in the web interface (Settings > About) or via CLI command 'ppdmcli version'Check Version:
ppdmcli versionVerify Fix Applied:
Confirm version is 19.22 or higher and test that low-privileged users cannot perform administrative actions📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation events in PowerProtect audit logs
- Multiple failed login attempts followed by successful administrative actions from same user
Network Indicators:
- Unusual administrative API calls from non-administrative user accounts
- Traffic patterns suggesting privilege escalation attempts
