Technical details

A path traversal vulnerability (CWE-22) exists in the Lenovo App Store (distributed in China) for Windows. The flaw allows a local authenticated user to bypass directory restrictions, potentially leading to arbitrary code execution. The attack requires local access to the machine and some level of user interaction. The vulnerability is addressed in version 9.0.2930.0514 and later. The CVSS 3.1 score of 7.3 reflects high impact to confidentiality, integrity, and availability, though it is limited by the requirement for local access and user interaction.
