CVE-2021-41065
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.53%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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. Listary will automatically access the named pipe and the attacker will be able to duplicate the victim's token to impersonate him. This exploit is valid in certain Windows versions (Microsoft has patched the issue in later Windows 10 builds).
