Command Injection in Dell PowerProtect Data Domain DD OS

IdentifiersCVE-2026-22761CWE-77

CVE-2026-22761 is a command injection vulnerability affecting Dell PowerProtect Data Domain products running vulnerable Data Domain Operating System (DD OS) versions. The provided content states that affected products include Dell PowerProtect Data Domain appliances, Data Domain Virtual Edition (DDVE), Dell APEX Protection Storage, Data Domain Management Center, and PowerProtect DP Series Appliance deployments that incorporate vulnerable DD OS versions. Dell describes the issue as a command injection flaw that can be exploited by a high-privileged attacker with remote access, resulting in arbitrary command execution with root privileges. The affected DD OS feature-release range is 7.7.1.0 through 8.6.0.0, and the issue is remediated in DD OS 8.6.1.10 and 8.7.0.0 or later. The vulnerable function or specific parameter handling path is not identified in the provided content.

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 command execution as root on the affected system. This implies full compromise of the underlying appliance or virtual instance, including the ability to alter system state, access or manipulate protected backup data, install persistence, disrupt backup and recovery operations, and potentially use the compromised platform for further movement within the environment. The provided content characterizes the issue with a CVSS score of 6.7 and notes that exploitation requires high privileges.

Mitigation

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

If immediate patching is not possible, reduce exposure by restricting remote administrative access to trusted management networks and limiting high-privilege account use to only necessary administrators. Monitor for suspicious command execution and administrative activity on affected Data Domain systems, and review access controls around interfaces reachable by remote privileged users. However, the provided content does not include vendor-specific temporary mitigations; patching to a fixed version is the primary mitigation.

Remediation

Patch, then assume compromise.

Upgrade affected Dell PowerProtect Data Domain/DD OS deployments to a remediated release. The provided content states that CVE-2026-22761 is fixed in DD OS 8.6.1.10 and 8.7.0.0 or later for affected feature releases. It also states that PowerProtect DP Series Appliance issues tied to this CVE are remediated in version 2.7.9 with DD OS 8.3.1.30. Organizations should apply the Dell-provided fixed versions appropriate to their release track and product deployment.
