High impact if exploited, but EPSS currently rates exploitation as unlikely (1.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
<p>An elevation of privilege vulnerability exists when the Shell infrastructure component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p> <p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.</p> <p>The update addresses the vulnerability by correcting the way in which the Shell infrastructure component handles objects in memory and preventing unintended elevation from lower integrity application.</p>
