📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
A read-only user gains full administrative control over the ONTAP Select Deploy system, potentially compromising the entire storage management infrastructure, modifying configurations, accessing sensitive data, or disrupting operations.
Likely Case
A malicious insider or compromised read-only account escalates to administrative privileges, enabling unauthorized configuration changes, data access, or system manipulation within the ONTAP Select Deploy environment.
If Mitigated
With proper access controls and monitoring, the impact is limited to attempted privilege escalation that can be detected and blocked before successful exploitation.
🎯 Exploit Status
Exploitation requires an authenticated read-only user account. The vulnerability is in the privilege management logic of the administration utility.
