Description
Ahsay AhsayCBS 9.1.4.0 allows an authenticated system user to inject arbitrary Java JVM options. Administrators that can modify the Runtime Options in the web interface can inject Java Runtime Options. These take effect after a restart. For example, an attacker can enable JMX services and consequently achieve remote code execution as the system user.
