vm2 is an open source vm/sandbox for Node.js. In vm2 prior to version 3.10.2, `Promise.prototype.then` `Promise.prototype.catch` callback sanitization can be bypassed. This allows attackers to escape the sandbox and run arbitrary code. In lib/setup-sandbox.js, the callback function of `localPromise.prototype.then` is sanitized, but `globalPromise.prototype.then` is not sanitized. The return value of async functions is `globalPromise` object. Version 3.10.2 fixes the issue.

This critical sandbox escape vulnerability affects the Node.js library and can be abused to execute commands. Immediate patching is recommended.

The version of the Node.js module vm2 installed on the remote host is prior to 3.10.2. It is, therefore affected by a sandbox breakout vulnerability due to a flaw with the `Promise.prototype.then` and `Promise.prototype.catch` callback sanitization. An unauthenticated, remote attacker can exploit this, to escape the sandbox and run arbitrary code.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
