Argument Injection in Dell PowerProtect Data Domain DD OS

IdentifiersCVE-2026-35153CWE-88· Improper Neutralization of…

CVE-2026-35153 is an improper neutralization of argument delimiters vulnerability (argument injection) in Dell PowerProtect Data Domain products running vulnerable Data Domain Operating System (DD OS) versions. Affected products include Dell PowerProtect Data Domain appliances, Data Domain Virtual Edition (DDVE), Dell APEX Protection Storage, and Data Domain Management Center. According to the provided content, affected versions are DD OS feature releases 7.7.1.0 through 8.7.0.0, DD OS LTS2025 releases 8.3.1.0 through 8.3.1.20, and DD OS LTS2024 releases 7.13.1.0 through 7.13.1.60. The flaw allows improper handling of command argument delimiters, enabling a high-privileged local attacker to inject unintended arguments into a command path and potentially reach arbitrary command execution as root.

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 can lead to arbitrary command execution with root privileges on the affected system. This implies full compromise of the underlying appliance or virtual instance, including the ability to execute privileged OS commands, alter system state, access protected data handled by the platform, and potentially disrupt backup and recovery operations.

Mitigation

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

If immediate patching is not possible, reduce exposure by strictly limiting local access to trusted administrators only, minimizing the number of high-privileged accounts, enforcing least privilege, monitoring privileged command execution and administrative activity, and restricting shell or console access paths to the appliance or instance. Because the vulnerability requires high privileges and local access, operational controls around administrator access are the primary mitigation until patched. The content does not provide any vendor-specific workaround beyond upgrading.

Remediation

Patch, then assume compromise.

Upgrade to a remediated Dell DD OS release. The provided content states fixes are available in DD OS 8.6.1.10 and 8.7.0.1 or later for affected feature-release trains, in DD OS 8.3.1.30 or later for LTS2025, and in DD OS 7.13.1.70 or later for LTS2024. Where applicable, use vendor-provided fixed builds for affected PowerProtect Data Domain platforms and related deployments running vulnerable DD OS versions.
