Incorrect file permissions on the packaged Nipper executable file in Zoho ManageEngine OpManager 12.4.072 and Firewall Analyzer 12.4.072 allow local users to elevate privileges to root by overwriting this file with a malicious payload.
During installation, installed file permissions are set to allow anyone to modify those files.
