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 access control vulnerability in the RBAC. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to information tampering.
AnalysisAI
Improper access control in the RBAC implementation of Dell PowerProtect Data Domain allows a low-privileged authenticated remote attacker to tamper with information beyond their authorized role scope. Affected releases span the main 7.7.1.0-8.6 line and three LTS tracks covering LTS2024, LTS2025, and LTS2026. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid low-privileged account on the Dell PowerProtect Data Domain appliance and network-level access to its management interface (AV:N/PR:L per CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N accurately reflects a constrained-impact vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a valid low-privileged Data Domain account - such as a backup operator or monitoring user - sends a crafted request to a management API endpoint that performs insufficient role validation, exploiting the RBAC gap to modify configuration records, job definitions, or retention policies outside their authorized scope. No public proof-of-concept code is known, so exploitation currently requires independent discovery of the specific endpoint and parameter manipulation required. |
| Remediation | Apply the update detailed 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. |
