Root code execution via unvalidated shared-object path
Published Mar 16, 2020 · Updated Aug 4, 2024
Local privilege escalation in VMware Workstation 15.x before 15.5.2 and Fusion 11.x before 11.5.2 allows local users to execute code as root. The Virtual Printer module loads a shared object from a user-supplied path without validating that path, placing low-privileged code in a root process. Exploitation requires nonadministrative access to a Linux guest with virtual printing enabled, which is disabled by default.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
