Technical details
This vulnerability is an incorrect authorization flaw in Dell PowerStore that allows authenticated users with low privileges to invoke administrator-only operations without proper authorization checks. The attack vector is network-based and requires prior authentication but no additional user interaction. By exploiting this weakness, an attacker can escalate their privileges from a low-privilege account to administrative level, gaining full control over the storage appliance.
