Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, 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 use of less trusted source vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to information tampering.
AnalysisAI
Dell PowerProtect Data Domain's handling of a less-trusted data source allows a remote, high-privileged attacker to perform limited information tampering, classified under CWE-348. Affected are multiple release trains spanning versions 7.7.1.0 through 8.7, including LTS2024, LTS2025, and LTS2026 long-term support branches. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already possess high-privileged (administrative) credentials on the Dell PowerProtect Data Domain appliance and have remote network access to its management interface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 2.7 (Low) accurately reflects the constrained threat model: AV:N indicates network reachability, but PR:H demands the attacker already hold high-privileged access to the appliance, which dramatically reduces the exploitable population. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already obtained high-privileged administrative credentials to a Dell PowerProtect Data Domain appliance - through credential theft, reuse, or insider access - connects remotely to the management interface and submits data via a less-trusted input channel that the system incorrectly prioritizes, allowing modification of information that should be authoritative or system-controlled. No public proof-of-concept exploit code has been identified at the time of this analysis. |
| Remediation | The primary remediation is to apply the patched release identified in Dell Security Advisory DSA-2026-278, available at 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. |
