            description:     %q{
A NoSQL injection occurs when a value originating from the client's request is
used within a NoSQL call without prior sanitisation.

This can allow cyber-criminals to execute arbitrary NoSQL code and thus steal data,
or use the additional functionality of the database server to take control of
further server components.

Arachni discovered that the affected page and parameter are vulnerable. This
injection was detected as Arachni was able to discover known error messages within
the server's response.

            remedy_guidance: %q{
The most effective remediation against NoSQL injection attacks is to ensure that
NoSQL API calls are not constructed via string concatenation that includes
unsanitized data.

Sanitization is best achieved using existing escaping libraries.
