== Noncompliant Code Example
|
|
|
|
When url query parameters are parsed by the https://www.npmjs.com/package/qs[qs] module for instance (it's the case by default with express.js framework) then it's possible to inject objects in the URL:
|
|
|
|
----
|
|
function (req, res) {
|
|
let query = { user: req.query.user, city: req.query.city };
|
|
|
|
db.collection("users")
|
|
.find(query) // Noncompliant: http://website/?user=admin&city[%24ne]=
|
|
.toArray((err, docs) => { });
|
|
}
|
|
----
|
|
|
|
== Compliant Solution
|
|
|
|
Make sure to validate the input types to only handle Strings:
|
|
|
|
----
|
|
function (req, res) {
|
|
let query = { user: req.query.user.toString(), city: req.query.city.toString() };
|
|
|
|
db.collection("users")
|
|
.find(query) // Compliant
|
|
.toArray((err, docs) => { });
|
|
}
