Technical details
An insecure inherited permissions vulnerability (CWE-277) exists in Lenovo Legion Zone (versions prior to 2.0.26) and Lenovo App Store (versions prior to 9.0.29) for Windows. The flaw is triggered when the applications are installed on a non-system partition, where default folder permissions may allow low-privileged local users to modify application binaries or configuration files. An attacker with local access can exploit these weak permissions to replace legitimate files with malicious code, leading to arbitrary code execution with the privileges of the application or the user running it. The vulnerability is specific to the Chinese market distribution of these tools. Users are advised to update to the latest versions to remediate the risk.
