IdentifiersCVE-2026-35073CWE-78· Improper Neutralization of Special…

CVE-2026-35073 is an OS command injection vulnerability in Dell PowerProtect Data Domain Data Domain Operating System (DD OS). According to the provided content, affected versions include feature releases 7.7.1.0 through 8.7.0.0, LTS2025 releases 8.3.1.0 through 8.3.1.20, and LTS2024 releases 7.13.1.0 through 7.13.1.60. The flaw is described as improper neutralization of special elements used in an OS command, allowing a high-privileged attacker with local access to inject arbitrary commands. Successful exploitation can result in execution of attacker-controlled commands with root privileges on the appliance.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary OS command execution as root on the affected Data Domain system. This can lead to full compromise of the appliance, including unauthorized modification of system state, access to sensitive backup data, disruption of backup and recovery operations, and use of the system as a privileged foothold for further actions.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, limit local access to trusted administrators only, minimize the number of high-privileged accounts on the appliance, and restrict administrative access paths through strong access control and monitoring. Because the issue requires high privileges and local access, reducing shell or console access and closely auditing privileged activity can reduce exposure until upgrades are applied. The provided content does not specify any vendor-supplied workaround beyond upgrading.

Remediation

Patch, then assume compromise.

Upgrade affected systems to a fixed release. The provided content states Dell remediated CVE-2026-35073 in DD OS 8.6.1.10 and 8.7.0.1 or later for feature releases, 8.3.1.30 or later for LTS2025, and 7.13.1.70 or later for LTS2024. Systems running vulnerable versions should be updated to the appropriate fixed version from Dell's advisory guidance.
