Title: Microsoft Windows WebDAV Scripted Request Vulnerability
Severity: HIGH
Description:
WebDAV is an extension of the HTTP protocol. It enables remote users to manage and collaboratively edit files on remote web servers.
Microsoft Data Access Component Internet Publishing Provider fulfills WebDAV requests. The action it takes is dependent on the type of WebDAV request being made.
Due to the Microsoft Data Access Component Internet Publishing Provider's mishandling of WebDAV requests, a remote attacker could have requests fulfilled with the privileges of a local user.
This vulnerability exists because the Microsoft Data Access Component Internet Publishing Provider fails to properly determine the origin of WebDAV requests, subsequently bypassing security zone restrictions. Therefore, a script initiating WebDAV requests will be executed by the MDACIPP in the local user context.
An attacker could compose a web page or HTML email containing a malicious script. Once accessed, the script would run locally on the user's system. The script could be devised to launch WebDAV requests for resources in the user's domain. Due to the handling of WebDAV requests, the requested resources may be revealed to the attacker depending on the permissions the user has within his domain. If the user has permissions to add, delete, change, etc. the files, the attacker could take such actions on a target host.
If successfully exploited, this vulnerability could lead to the disclosure and compromise of sensitive information assisting in further attacks against the host.
