Vulnerability details

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to the way Windows handles calls to Clipboard Service. A local user can create a malicious application, launch it on the system and run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system.
