Description

An issue was discovered in Listary through 6. An attacker can create a \\.\pipe\Listary.listaryService named pipe and wait for a privileged user to open a session on the Listary installed host.

This exploit is valid in certain Windows versions (Microsoft has patched the issue in later Windows 10 builds).
