Nucleus CMS GLOBALS[DIR_LIBS] Parameter Remote File Include Vulnerability

An attacker can exploit this issue to include an arbitrary remote file containing malicious PHP code and execute it in the context of the webserver process. This may allow the attacker to compromise the application and the underlying system; other attacks are also possible.
