What happened

Dell PowerProtect Data Domain Management Center has a Missing Authorization flaw (CWE-862 class), allowing a low-privileged remote attacker to trigger unauthorized operations on managed systems.

Why it is dangerous: Successful exploitation could lead to unauthorized changes on managed Data Domain systems, potentially disrupting or compromising backup and data protection. Organizations running this management center with remote access enabled are most at risk.
