Attack-Flow Graph

Impact Analysis

If exploited, this vulnerability allows an attacker to execute arbitrary commands with root privileges on the affected Dell PowerProtect Data Domain system.

This could lead to full system compromise, unauthorized access to sensitive data, disruption of services, and potential further attacks within the network.

Executive Summary

This vulnerability exists in Dell PowerProtect Data Domain versions 7.7.1.0 through 8.6, including certain LTS2025 and LTS2024 release versions. It is a missing authentication issue for a critical function, which means that an unauthenticated attacker with remote access could potentially exploit it.

Exploitation requires an authenticated user to perform a specific action, but once exploited, it could lead to arbitrary command execution with root privileges on the affected system.

Compliance Impact

This vulnerability allows an unauthenticated attacker with remote access to potentially execute arbitrary commands with root privileges on affected Dell PowerProtect Data Domain systems. Such unauthorized access and control could lead to unauthorized disclosure, modification, or destruction of sensitive data.

As a result, exploitation of this vulnerability could compromise the confidentiality, integrity, and availability of data, which are critical requirements under common standards and regulations such as GDPR and HIPAA.

Organizations using affected versions may face increased risk of non-compliance with these regulations if the vulnerability is exploited, due to potential data breaches or loss of data integrity.
