Security readout for executives and security teams
Plain-English summary
This vulnerability affects Dell PowerProtect Data Domain systems in specified Feature Release and LTS release ranges. A highly privileged local user could abuse command argument handling to execute commands as root. Business urgency is moderate: exploitation requires existing high privileges and local access, but successful abuse could fully compromise a backup appliance.
Executive priority
Treat this as a timely backup-infrastructure hardening issue. It is not described as remotely exploitable or actively exploited, but root-level compromise of backup systems can materially affect recovery, resilience, and incident response.
Technical view
CVE-2026-35153 is a CWE-88 argument injection flaw in Dell PowerProtect Data Domain. The CVSS v3.1 score is 6.7, with local attack vector, low complexity, high privileges required, and high confidentiality, integrity, and availability impact. A successful attacker may achieve arbitrary command execution with root privileges.
Likely exposure
Organizations running Dell PowerProtect Data Domain Feature Release 7.7.1.0 through 8.6.0.0, version 8.7.0.0, LTS2025 8.3.1.0 through 8.3.1.20, or LTS2024 7.13.1.0 through 7.13.1.60 may be exposed.
Exploitation context
The available sources do not report active exploitation, and the CVE is not listed as KEV in the provided data. Exploitation requires local access and high privileges, making insider misuse, compromised administrator accounts, or post-compromise escalation the main concerns.
Researcher notes
Evidence is limited to the CVE record and Dell advisory reference. The affected range details are specific, but the provided bundle does not include fixed versions or workaround text. Avoid assuming exploit availability or remediation details beyond Dell’s published advisory.
Mitigation direction
- Identify all Dell PowerProtect Data Domain systems and their installed release versions.
- Review Dell advisory DSA-2026-060 for vendor-designated updates or remediation instructions.
- Prioritize remediation on internet-connected management paths or high-value backup environments.
- Restrict local and administrative access to trusted personnel only.
- Monitor privileged account activity on affected appliances.
Validation and detection
- Compare installed versions against the affected ranges listed in the CVE record.
- Confirm whether each appliance is Feature Release, LTS2025, or LTS2024.
- Check Dell advisory DSA-2026-060 for fixed release guidance.
- Review administrative access logs for unusual local privileged activity.
- Document remediation status for each Data Domain appliance.

Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')
Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
