Vulnerability Details

Dell PowerProtect Data Domain with Data Domain Operating System (DD OS) of Feature Release versions 8.4 through 8.5 contain an improper authentication vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access. The vulnerability is classified under CWE-287, which deals with improper authentication mechanisms.

The CVSS score for this vulnerability is 6.6, which is categorized as medium severity. The attack vector is classified as network-based, with high complexity required for successful exploitation and high privileges needed. User interaction is not required, which further increases the risk as attackers may execute their attacks remotely without any user intervention.

The vulnerability was published on April 17, 2026, and it is important for organizations to stay informed about this vulnerability and its implications. Timely remediation will help mitigate risks associated with unauthorized access.

Technical Analysis

The root cause of the vulnerability lies in the improper authentication mechanism implemented within the affected versions of the Data Domain Operating System. Attackers can exploit this flaw remotely, leveraging their high privileges to gain unauthorized access. The attack complexity is deemed high, requiring a knowledgeable attacker to succeed.

This vulnerability requires high privileges for exploitation, which means that only users with elevated access rights can potentially exploit the flaw. No user interaction is required, making it easier for attackers to execute their attacks without the need for any action from legitimate users.

The impacts of this vulnerability are significant, as it can lead to high confidentiality, integrity, and availability impacts. An attacker gaining unauthorized access could alter, disclose, or disrupt sensitive data and services, leading to severe consequences for affected organizations.

Risk & Impact Analysis

Organizations utilizing Dell PowerProtect Data Domain systems running the affected versions are at risk of unauthorized access that could lead to significant data compromise. The blast radius of this vulnerability could extend to critical data and services, potentially affecting operations and compliance with data protection regulations.

The urgency to address this vulnerability is moderate, as the CVSS score of 6.6 indicates that while the risk is not the highest, it is still significant enough to warrant prompt attention. Organizations should incorporate this vulnerability into their risk assessments and prioritize it in their patch cycles.

The publication of this vulnerability indicates a growing trend in the exploitation of improper authentication mechanisms in enterprise systems, emphasizing the need for robust security measures and continuous monitoring to detect potential threats.

Exploitation Status

Affected Versions
