NoSQL Injection into DynanmoDB

Asked 2019-Oct-12 at 17:51

Does anyone know if there are any known no SQL vulnerabilities with the 'Dynogels' library when interacting with a NO SQL database.

Not using any advanced queries, only bog standard with the existing methods. query(), where(), equals() etc.

ANSWER

Answered 2019-Oct-12 at 17:51

Maybe not really a known issue, but dealing with input data in general, and saving it into whatever database you always have to sanitise your data to prevent injections.

As you are dealing with JSON a lot in DynanmoDB, be especially careful when deserialising user input to JSON objects and inserting or updating these objects directly into a NoSQL database. For example make sure the user cannot add extra fields into the JSON object.

It al depends on how you validate your user input.

I think it is safe to say that NoSQL databases access the database more in terms of functions, and JSON objects. You have to worry less about SQL injections than traditional string based access (TSQL) databases.

QUESTION

Unable to query using only the rangeKey

Asked 2018-Mar-02 at 06:09

I just started working on DynamoDB so please forgive me if the following seems like a dumb mistake.

I have a model with a hashKey and a rangeKey. Let's name these as HASH and RANGE respectively.
A global secondary index: GlobalIndex is added to the model as well.

Now what I want is to get the list of records by rangeKey. I don't want to use the scan operation since it impacts the performance. I am unable to achieve this with the query operation. Trying to achieve something like this with dynogels.

Any kind of help would be really helpful.

Thanks.

It was a mistake on my end. The index has the same hash key and range key as the table. The GitHub issue thread for the same: https://github.com/clarkie/dynogels/issues/137

You need to set context.callbackWaitsForEmptyEventLoop = false in your Lambda function so that Lambda will properly shut down when using DAX.

Node code not blocking?

Asked 2017-Aug-02 at 03:47

I have a constructor which fetches data from a DynamoDB using promisified dynogels to populate part of the object's properties. So after instantiating an instance of that object, the property is not populated, here is an extract of the code:

...

ANSWER

Answered 2017-Aug-02 at 03:47

You generally don't want to carry out an asynchronous operation in a constructor because it complicates creating an object and then knowing when the async operation is done or if it had an error because you need to allow the constructor to return the object, not a promise that would tell you when the async operation was done.

There are several possible design options:

Option #1: Don't do any async operation in the constructor. Then, add a new method with an appropriate name that does the async operation and returns a promise.

In your case, you could make the new method be scan() that returns a promise. Then, you'd use your object by creating it and then calling scan and then using the returned promise to know when the data is valid.

I don't know TypeScript myself, so I'll give a modified version of your code, but the concept is the same either way whether it's TypeScript or plain Javascript:

I am trying to optimise the following scans into a single scan (or query). The only way I see is to use to use a OR comparator using DynamoDB. I am using dynogels (fork of vogels) in my application but sadly I am not aware of any OR query functionality in there.

Vulnerabilities

Install dynogels

First, you need to configure the AWS SDK with your credentials. When running on EC2 it's recommended to leverage EC2 IAM roles. If you have configured your instance to use IAM roles, Vogels will automatically select these credentials for use in your application, and you do not need to manually provide credentials in any other format. You can also directly pass in your access key id, secret and region.
It's recommended not to hard-code credentials inside an application. Use this method only for small personal scripts or for testing purposes.
