CVE-2019-10758 is a remote code execution vulnerability in mongo-express before version 0.54.0. The flaw is exposed through endpoints that invoke the toBSON method. Due to unsafe use of the vm dependency, attacker-controlled input can be evaluated in a non-safe execution context, enabling execution of operating system commands instead of being confined to a secure sandbox. The issue effectively turns BSON-related request handling into a code execution primitive on affected mongo-express deployments.

This repository is a proof-of-concept (PoC) exploit for CVE-2019-10758, a remote code execution vulnerability in mongo-express <=0.53.0. The repository contains three files: a README.md with setup and exploitation instructions, a main.js script that crafts the exploit payload, and a package-lock.json for dependencies. The exploit works by sending a specially crafted payload to the /checkValid endpoint of a locally running mongo-express instance, leveraging server-side JavaScript injection to execute arbitrary system commands. The provided payload demonstrates launching the Calculator app on macOS, but any command could be executed. The exploit requires the vulnerable mongo-express to be running with default credentials and accessible on http://localhost:8081. The main.js file is the core exploit script, while the README provides both a cURL-based and script-based exploitation method. No detection or fake code is present; this is a functional PoC exploit.
