Description
Apache NetBeans (incubating) 9.0 NetBeans Proxy Auto-Configuration (PAC) interpretation is vulnerable for remote command execution (RCE). Using the nashorn script engine the environment of the javascript execution for the Proxy Auto-Configuration leaks privileged objects, that can be used to circumvent the execution limits. If a different script engine was used, no execution limits were in place. Both vectors allow remote code execution.
