CVE-2026-22761
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell PowerProtect Data Domain, versions 8.5 through 8.6 contain a command injection vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to arbitrary command execution with root privileges.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell PowerProtect Data Domain versions 8.5 through 8.6 contain a command injection vulnerability. A high-privileged attacker with remote access to the affected system can exploit insufficient input validation to inject and execute arbitrary operating system commands with root privileges.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine Data Domain OS versionAccess the system console or management interface and run the command: `version` or `sysadmin version` to display the installed Data Domain Operating System version.Affected if The reported version is >= 7.7.1.0 and < 8.6.1.0, or < 2.7.9 for the DP Series Appliance.
-
Check PowerProtect DP Series Appliance versionFrom the management CLI or GUI, navigate to system information or run: `system show version` or check the appliance firmware version through the management interface.Affected if The installed firmware version is < 2.7.9.
-
Verify remote administrative access exposureReview the system's access configuration by checking: `network interface` show commands or review the admin user list with `user list` to confirm which remote IP addresses or networks have high-privileged administrative access.Affected if Remote administrative (admin/root) access is enabled and reachable from untrusted networks.
-
Confirm high-privileged user accountsExecute `admin` or `user list` command to enumerate administrative accounts. This vulnerability requires a high-privileged attacker, so verify which accounts have root-level or administrative privileges.Affected if Any high-privileged administrative accounts exist on the system.
A system is affected if it runs Dell Data Domain OS version 7.7.1.0 through 8.6.0.x or PowerProtect DP Series Appliance firmware below 2.7.9, and has accessible high-privileged administrative accounts.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.7.98.6.1.0
Apply vendor-provided patches or upgrade to a version beyond 8.6 as specified by Dell's security advisory. Restrict administrative access and monitor for suspicious command activity until patching is complete.
Data Domain OS: 8.6.1.0 or later; PowerProtect DP Series Appliance: 2.7.9 or later
- Identify the specific Dell PowerProtect Data Domain or PowerProtect DP Series Appliance model and current software version
- For Data Domain Operating System: Plan upgrade to version 8.6.1.0 or later
- For PowerProtect DP Series Appliance: Plan upgrade to version 2.7.9 or later
- Review Dell upgrade documentation and release notes for prerequisites
- Schedule maintenance window as upgrades may require system downtime
- Backup current configuration before proceeding
- Follow Dell's recommended upgrade procedure for the specific appliance model
- Verify successful upgrade and confirm the vulnerability is remediated
