This repository provides a functional exploit chain for CVE-2026-15409 (SonicWall SMA1000 SSRF) and CVE-2026-15410 (root privilege escalation). The exploit leverages SSRF to access internal Erlang distribution services, authenticates using a hardcoded cookie, and achieves RCE via Erlang's `os:cmd/1`, then escalates to root via a path traversal in the AMC.

https://github.com/remmons-r7/rapid7-CVE-2026-15409

This exploit achieves remote code execution (RCE) on SonicWall SMA 1000 appliances by tunneling Erlang distribution protocol traffic through a WebSocket proxy to interact with an internal Erlang node (localhost:1050). It leverages unauthenticated access to the WorkPlace service and hardcoded Erlang node cookies to execute arbitrary commands via RPC calls.
