Detailsinfo

A vulnerability classified as problematic has been found in Dell PowerProtect Data Domain up to 7.7.1.0/8.8/7.13.1.80/8.3.1.40/8.6.1.20. This affects an unknown code. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. The summary by CVE is:

Dell PowerProtect Data Domain, Feature Release versions 7.7.1.0 through 8.8, LTS2024 release versions 7.13.1.0 through 7.13.1.80, LTS2025 release versions 8.3.1.0 through 8.3.1.40, LTS2026 release versions 8.6.1.0 through 8.6.1.20, contain a Path Traversal vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Denial of service.

The advisory is shared at dell.com. This vulnerability is uniquely identified as CVE-2026-90726 since 09/13/2026. The exploitability is told to be easy. An attack has to be approached locally. The exploitation needs additional levels of successful authentication. Neither technical details nor an exploit are publicly available.
