CVE-2026-26358
📋 TL;DR
Dell Unisphere for PowerMax versions 10.2 contain a missing authorization vulnerability that allows low-privileged remote attackers to gain unauthorized access. This affects organizations using Dell Unisphere for PowerMax storage management software. Attackers could potentially access sensitive storage management functions they shouldn't have permission to use.
💻 Affected Systems
- Dell Unisphere for PowerMax
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could gain administrative control over PowerMax storage systems, potentially accessing, modifying, or deleting critical storage data and configurations.
Likely Case
Low-privileged users could escalate privileges to perform unauthorized storage management operations, potentially disrupting storage services or accessing sensitive data.
If Mitigated
With proper network segmentation and access controls, impact would be limited to authorized users gaining additional privileges within their existing access scope.
🎯 Exploit Status
Exploitation requires existing low-privileged access but authorization bypass is typically straightforward once access is obtained.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply security update from DSA-2026-102
