Critical by CVSS (9.8), but no sign of active exploitation.

Description

An elevation of privilege vulnerability exists in ManageEngine ADSelfService Plus before build 6003 because it does not properly enforce user privileges associated with a Certificate dialog. This vulnerability could allow an unauthenticated attacker to escalate privileges on a Windows host. An attacker does not require any privilege on the target system in order to exploit this vulnerability. One option is the self-service option on the Windows login screen. Upon selecting this option, the thick-client software is launched, which connects to a remote ADSelfService Plus server to facilitate self-service operations. An unauthenticated attacker having physical access to the host could trigger a security alert by supplying a self-signed SSL certificate to the client. The View Certificate option from the security alert allows an attacker to export a displayed certificate to a file. This can further cascade to a dialog that can open Explorer as SYSTEM. By navigating from Explorer to \windows\system32, cmd.exe can be launched as a SYSTEM.
