Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.6, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an improper neutralization of special elements used in an OS command ('OS command Injection') vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Command execution.
AnalysisAI
OS command injection in Dell PowerProtect Data Domain enables a high-privileged local attacker to execute arbitrary operating system commands on the backup appliance, achieving full command execution within the Data Domain OS (DDOS). The flaw spans the general release track (7.7.1.0-8.6) and three LTS streams (LTS2024, LTS2025, LTS2026), indicating a shared vulnerable code path across a wide version surface. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two concrete prerequisites: (1) high-privileged (PR:H) authenticated access to the appliance, consistent with an administrative account or equivalent privileged role within DDOS, as confirmed by the CVSS vector; and (2) local access (AV:L), meaning the attacker must have an authenticated local session - physical console, SSH, or equivalent - rather than exploiting an exposed unauthenticated network service. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 6.7 score accurately reflects the constrained exploitability profile: local attack vector (AV:L) combined with high-privilege requirement (PR:H) means an attacker must already possess admin-level authenticated access before exploitation is possible. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained high-privileged credentials to a Dell PowerProtect Data Domain appliance - through insider access, credential theft, or as part of a broader compromise chain - authenticates to the DDOS management CLI or local shell interface. The attacker submits a crafted input string containing injected OS command sequences (e.g., via semicolons, backticks, or shell metacharacters) to a vulnerable command-processing function. … |
| Remediation | Apply the vendor-supplied patch as documented in Dell advisory DSA-2026-278 (https://www.dell.com/support/kbdoc/en-us/000481268/dsa-2026-278-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities). … Detailed patch versions, workarounds, and compensating controls in full report. |
