CVE-2022-24434 is a denial-of-service vulnerability in the dicer package affecting all reported versions, including deployments where it is bundled into downstream products such as HCL Digital Experience 9.5 containers. The issue is triggered when a remote attacker sends a maliciously modified multipart form payload to a Node.js service that uses dicer for parsing. Available reporting attributes the crash to HeaderParser behavior during form processing. Successful exploitation causes the Node.js service to terminate, enabling repeated service crashes through repeated malicious requests.

This repository is a Proof-of-Concept (PoC) for CVE-2022-24434, a vulnerability in the Dicer npm package (version 0.3.1). The repository contains three files: a README with setup and usage instructions, 'server.js' which runs a local HTTP server using the vulnerable Dicer parser, and 'dicer_poc.js' which is the exploit script. The exploit works by sending a series of crafted HTTP POST requests with various malformed multipart/form-data bodies to the server at http://127.0.0.1:3000. These requests are designed to trigger edge cases and potential crashes or memory issues in the Dicer parser, demonstrating the vulnerability. The PoC is intended for local testing and research, requiring the Dicer source at the specified vulnerable version. No real-world targets or external endpoints are included; all testing is performed against a local server instance.
