Description
|
|
***********
|
|
|
|
WEBrick Httpd server has directory traversal security vulnerability.
|
|
|
|
WEBrick is an HTTP server library written in Ruby that uses servlets to extend its capabilities.
|
|
Built into WEBrick are four servlets, handling CGI, ERb, file directories, and a generic Proc servlet.
|
|
Ruby on Rails uses WEBrick as a quick and easy webserver to start developing your Rails applications.
|
|
However, for whatever ease of development WEBrick adds to your application, it is generally considered not suitable for any production environment.
|
|
|
|
|
|
|
|
|
|
Details
|
|
*******
|
|
|
|
The following programs are vulnerable.
|
|
|
|
Programs that publish files using WEBrick::HTTPServer.new with the :DocumentRoot option
|
|
Programs that publish files using WEBrick::HTTPServlet::FileHandler
|
|
|
|
Affected systems are:
|
|
1. Systems that accept backslash (\) as a path separator, such as Windows.
|
|
2. Systems that use case insensitive filesystems such as NTFS on Windows, HFS on Mac OS X.
|
|
|
|
|
|
This vulnerability has the following impacts.
|
|
1. Attacker can access private files by sending a url with url encoded backslash (\). This exploit works only on systems that accept backslash as a path separator.
|
|
|
|
Example:
|
|
|
|
http://[server]:[port]/..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c..%5c/boot.ini
|
|
|
|
|
|
2. Attacker can access files that matches to the patterns specified by the :NondisclosureName option (the default value is [".ht*", "*~"]). This exploit works only on systems that use case insensitive filesystems.

Additional info
|
|
***************
|
|
|
|
WEBrick is used to build own HTTP servers and used in many applications such as Metasploit 3.1 and Karma Tools
|

|
|
|
