The vulnerability stems from Electerm's service accepting and executing unauthenticated requests. While exact function names aren't available in the provided data, Electron applications typically handle inter-process communication and network requests in the main process. The root cause would be a function that: 1) Listens on a network interface, 2) Accepts external commands, 3) Executes them without validation. The high confidence comes from the vulnerability description explicitly stating 'unverified request to electerms service' and the reproduction steps demonstrating RCE via HTTP requests.
