What is CVE-2019-12889?
CVE-2019-12889 is a high-severity vulnerability in n/a, published on 20 Aug 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
An unauthenticated privilege escalation exists in SailPoint Desktop Password Reset 7.2. A user with local access to only the Windows logon screen can escalate their privileges to NT AUTHORITY\System. An attacker would need local access to the machine for a successful exploit. The attacker must disconnect the computer from the local network / WAN and connect it to an internet facing access point / network. At that point, the attacker can execute the password-reset functionality, which will expose a web browser. Browsing to a site that calls local Windows system functions (e.g., file upload) will expose the local file system. From there an attacker can launch a privileged command shell.
