Critical Vulnerability in NestJS Devtools: Localhost RCE via...
Blog post from Socket
A critical vulnerability in the NestJS Devtools integration was discovered, allowing attackers to execute arbitrary code on local machines through a sandbox escape and Cross-Site Request Forgery (CSRF). This vulnerability exploits a long-standing security issue in browsers that permits websites to interact with local services, combined with a flawed sandbox that uses the Node.js `vm` module, which is not recommended for running untrusted code. Attackers can craft payloads to be executed by the local server, bypassing the Access-Control-Allow-Origin header and exploiting the lack of content-type checking. The vulnerability was addressed by implementing fixes such as using a different sandboxing solution, ensuring content-type checks, verifying request origins, and requiring an authentication token for connections. The incident highlights the persistent risks associated with local web servers and the delayed response of browsers in safeguarding end-users from such threats.
