Mitigating factors: URLScan, which is a part of the IIS Lockdown Tool will block this attack in its default configuration The vulnerability can only be exploited remotely if an attacker can Solution: The vendor has released the following patch.
back to top WebDAV stands for "Web-based Distributed Authoring and Versioning". Impact Any attacker who can reach a vulnerable web server can gain complete control of the system and execute arbitrary code in the Local System security context. Looking to get things done in web development? http://internetpasswordpro.com/windows-2000/windows-2000-default-permissions-vulnerability-oct-30.html Microsoft has released a new revision of the advisory which contains patches for Windows XP.
