list_vuln_exceptions returns API error

[peterjmcg]

Script to list vulnerability exceptions has recently (within last week) started returning API error :

C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/nexpose-7.1.1/lib/nexpose/ajax.rb:172:in request': NexposeAPI: GET request to /api/experimental/vulnerability_exceptions?_size=500&_page=0 failed. request body: (Nexpose::APIError) from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/nexpose-7.1.1/lib/nexpose/ajax.rb:35:inget' from C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/nexpose-7.1.1/lib/nexpose/vuln_exception.rb:25:in list_vuln_exceptions' from Exceptions.rb:59:in

'

Rapid7 support suggested opening issue in this forum, pointing out that the URI path name contains 'experimental'.

To reproduce:

(Parameters host, user, pass, port passed as input parameters).

@nsc = Nexpose::Connection.new(host, user, pass, port)

@nsc.login

puts("Successful login to #{host} at #{Time.now.strftime('%H:%M')}")

at_exit { @nsc.logout }

Check for vulnerability exceptions

puts("Checking vulnerability exceptions")

exceptions = @nsc.list_vuln_exceptions || []

Note: failure was first seen 2 days ago with client version 5.3.2 with error message complaining about date format. After upgrade to client 7.1.1 script still fails but with different error message (above).

This is caused by the official release of these endpoints (it is no longer experimental). The URI just needs to change. Patch in the works.

[peterjmcg]

Thanks. If you can give me the new URI I can try it.

See https://github.com/rapid7/nexpose-client/pull/313

New error message (with changed URI) : C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/nexpose-7.1.1/lib/nexpose/vuln_exception.rb:30:in list_vuln_exceptions': undefined methodcount' for nil:NilClass (NoMethodError) from Exceptions.rb:59:in `

I think _links needs to be links.

[ghost]

Indeed. Thanks.

[peterjmcg]

Also _resources to resources. Then it works ok.

[peterjmcg]

Also, you might want to mention in the release notes that the timestamps (expiration date etc) were changed from Date to Time. Could save some broken scripts.

Released v7.2.0 with the fix.
