Detailsinfo

A vulnerability was found in Huawei Mate 20, Mate 20 Pro, Hima-L29C, Laya-AL00EP, OxfordS-AN00A and Tony-AL00B (Smartphone Operating System). It has been classified as critical. This affects an unknown code block. 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 confidentiality, integrity, and availability.
