An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to arbitrary command execution with root privileges. This is a critical severity vulnerability as it allows an attacker to take complete control of the system. Dell recommends customers to upgrade at the earliest opportunity.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-287"],"vendors":[],"products":[],"references":[{"url":"https://www.dell.com/support/kbdoc/en-us/000515178/dsa-2026-416-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":{"summary":"An improper authentication flaw (CWE-287) in Dell PowerProtect Data Domain allows unauthenticated remote attackers to execute arbitrary commands as root across multiple affected versions (7.7.1.0–8.8, 7.13.1.0–7.13.1.80, 8.3.1.0–8.3.1.40, 8.6.1.0–8.6.1.20), enabling full system compromise.","exploitability":"Highly exploitable: no authentication or user interaction is required, and the vulnerability permits remote code execution with root privileges.","blast_radius":"Successful exploitation grants attackers complete control of the affected Data Domain system, risking data exfiltration, ransomware deployment, or lateral movement within backup infrastructure.","remediation":"Upgrade to Dell PowerProtect Data Domain LTS2026 release version 8.6.1.21 or later, LTS2025 release version 8.3.1.41 or later, LTS2024 release version 7.13.1.81 or later, or Feature Release version 8.9 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","auth-bypass","backup-systems","critical-severity"],"model":"garnet-coder","analyzedAt":"2026-10-28T10:02:41.842Z"}}
