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 uninitialized resource vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to information exposure.
AnalysisAI
Information exposure in Dell PowerProtect Data Domain across multiple release tracks allows a low-privileged local attacker to read sensitive residual data via an uninitialized memory resource (CWE-908). The flaw spans the mainline 7.7.1.0-8.7 branch and three LTS tracks (LTS2024, LTS2025, LTS2026), confirmed by Dell via advisory DSA-2026-278. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated local session on the Dell PowerProtect Data Domain appliance with at least low-level privileges, confirmed by the CVSS vector PR:L and AV:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.3 (Low) score is well-calibrated to the realistic risk profile: AV:L eliminates remote exploitation entirely, PR:L requires an authenticated foothold, and C:L means only partial data exposure rather than full system compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A low-privileged user with an existing local session on the Data Domain appliance - such as a restricted OS-level or application account - invokes a code path that reads from an uninitialized memory buffer, capturing residual data left by a prior process. The leaked contents could include configuration values, backup metadata, or other sensitive in-memory artifacts depending on timing and system state. … |
| Remediation | Consult Dell advisory DSA-2026-278 at https://www.dell.com/support/kbdoc/en-us/000481268/dsa-2026-278-security-update-for-dell-powerprotect-data-domain-multiple-vulnerabilities for the specific fixed versions applicable to each release track. … Detailed patch versions, workarounds, and compensating controls in full report. |
