VMware Workstation (12.x before 12.5.8) installer contains a DLL hijacking issue that exists due to some DLL files loaded by the application improperly. This issue may allow an attacker to load a DLL file of the attackers choosing that could execute arbitrary code.

Weakness

The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.

Extended Description

This might allow attackers to execute their own programs, access unauthorized data files, or modify configuration in unexpected ways. If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
