NVD · uneditedAn improper permission handling vulnerability was reported in Lenovo PC Manager that could allow a local attacker to perform arbitrary file deletions as an elevated user.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceLenovo PC Manager contains an improper permission handling vulnerability that allows a local attacker to perform arbitrary file deletions with elevated user privileges. The vulnerability stems from insufficient validation of file operation permissions, enabling a local attacker who already has some level of elevated access to manipulate the software into deleting files outside its intended scope.

Alternatively, navigate to the installation directory (typically C:\Program Files\Lenovo\Lenovo PC Manager\) and right-click the executable to view properties.Affected if A version number is displayed in the properties window.
-
Compare installed version to the affected rangeCompare the version found in step 2 against the vulnerable threshold: versions prior to 5.1.110.5082 are affected.Affected if The installed version is lower than 5.1.110.5082 (for example, 5.1.100.4051 or any 5.0.x.x release).
-
Check user permissions on the application directoryRight-click the Lenovo PC Manager installation folder (usually in Program Files), select Properties > Security, and review which users and groups have write or modify permissions.Affected if Any unprivileged or secondary user accounts have elevated write/modify permissions to the application directory.
A user is affected if Lenovo PC Manager is installed with a version lower than 5.1.110.5082 and the vulnerable file operation permissions are present.
