Detailsinfo

A vulnerability classified as problematic has been found in MediaTek MT6580, MT6739, MT6761, MT6762, MT6765, MT6768, MT6769, MT6771, MT6779, MT6781, MT6785, MT6789, MT6833, MT6853, MT6853T, MT6873, MT6875, MT6877, MT6879, MT6883, MT6885, MT6889, MT6891, MT6893, MT6895, MT6983, MT8163, MT8167, MT8168, MT8173, MT8185, MT8321, MT8362A, MT8365, MT8735, MT8735B, MT8765, MT8766, MT8768, MT8786, MT8788, MT8789, MT8791 and MT8797 (Chip Software). Affected is an unknown part of the component aee Daemon. 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.

The weakness was released 05/04/2022. The advisory is shared for download at corp.mediatek.com. This vulnerability is traded as CVE-2022-20101 since 10/12/2021. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.
