CVE-2017-7884 Information

Description

In Adam Kropelin adk0212 APC UPS Daemon through 3.14.14 the default installation of APCUPSD allows a local authenticated but unprivileged user to run arbitrary code with elevated privileges by replacing the service executable apcupsd.exe with a malicious executable that will run with SYSTEM privileges at startup. This occurs because of \RW NT AUTHORITY\Authenticated Users\ permissions for SYSTEMDRIVE\apcupsd\bin\apcupsd.exe.
