Improper Preservation of Permissions
A vulnerability exists in Trellix Agent for Windows version 5.7.8 and earlier, that allows local users, during install/upgrade workflow, to replace one of the Agent’s executables before it can be executed. This allows the user to elevate their permissions.
CWE-281 - Improper Preservation of Permissions
The software does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
