Kingdom: Input Validation and Representation
Input validation and representation problems ares caused by metacharacters, alternate encodings and numeric representations. Security problems result from trusting input. The issues include: "Buffer Overflows," "Cross-Site Scripting" attacks, "SQL Injection," and many others.
Query String Injection: MongoDB
Abstract
Insufficient validation of user input can enable an attacker to gain unauthorized access to sensitive information stored in a NoSQL database.
Explanation
MongoDB is a type of NoSQL database that supports JSON-oriented document storage format. An injection vulnerability occurs when:
1. PHP objects are passed in with HTTP GET and HTTP POST requests and are not inherently sanitized
2. No datatype checks are performed against the GET and POST parameters
3. A simple variable can be converted into array object by passing it as an array reference
Example: The following code finds all users with username passed through the request parameter.
Instead of passing a username string, an attacker could manipulate the query by requesting http://www.example.com?username[$ne]=foo. This allows the attacker to manipulate the query as below:
The lack of user input validation can allow the attacker to enumerate the list of all the authorized users in the system.

Example: The following code finds all users with username passed through the request parameter.
$collection->find(array("username" => $_GET['username']))Instead of passing a username string, an attacker could manipulate the query by requesting http://www.example.com?username[$ne]=foo. This allows the attacker to manipulate the query as below:
$collection->find(array("username" => array('$ne' => "foo")))The lack of user input validation can allow the attacker to enumerate the list of all the authorized users in the system.
