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 improper limitation of a pathname to a restricted directory ('path traversal') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to unauthorized file modification.
AnalysisAI
Unauthorized file modification in Dell PowerProtect Data Domain allows a high-privileged remote attacker to write files outside the intended restricted directory via path traversal. Affected across multiple release trains spanning versions 7.7.1.0 through 8.7, including LTS2024, LTS2025, and LTS2026 branches. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires high-privilege authentication (PR:H per CVSS vector) - the attacker must possess or obtain administrator-level credentials on the Dell PowerProtect Data Domain system before the traversal can be triggered. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The aggregated risk signals consistently indicate a low-priority issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained high-privilege credentials - whether through credential theft, insider threat, or prior compromise of an admin account - authenticates to the Dell PowerProtect Data Domain management interface over the network and submits a crafted request containing path traversal sequences. The appliance fails to sanitize the pathname, allowing the attacker to write or modify a file outside the intended restricted directory, potentially altering configuration files or stored metadata. … |
| Remediation | The primary remediation is to apply the patched firmware or software version released by Dell as part of 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. |
