Document Title:
===============
pdirl PHP Directory Listing 1.0.4 - Cross Site Scripting Web Vulnerabilities


References (Source):
====================

Release Date:
=============
2013-11-01


Vulnerability Laboratory ID (VL-ID):
====================================
1130


Common Vulnerability Scoring System:
====================================
3.4


Product & Service Introduction:
===============================
pdirl (PHPDirListing) is a tiny directory listing program. It is meant to be better looking and more useful than the 
directory listings produced by Apache. I didn`t want to reinvent the wheel so I looked for an existing PHP script and 
I ve found PHPDL by Greg Johnson, I added some features to it. (1.0.x is no longer based on PHPDL.)

Abstract Advisory Information:
==============================
An independent Vulnerability Laboratory Researcher discovered multiple web vulnerabilities in the pdirl PHP Listing 
v1.0.4 web-application.


Vulnerability Disclosure Timeline:
==================================
2013-11-01:    Public Disclosure (Vulnerability Laboratory)


Discovery Status:
=================
Published


Affected Product(s):
====================
Greg Johnson
Product: pdirl PHP Listing - Web Application 1.0.4


Exploitation Technique:
=======================
Remote


Severity Level:
===============
Medium


Technical Details & Description:
================================
Multiple client-side cross site scripting vulnerabilities are detected in the official pdirl PHP Directory Listing 
web-application.
The vulnerability allows remote attackers to manipulate via GET method web-application to browser requests 
(client-side).

The client-side cross site scripting web vulnerability is located in the vulnerable index.php file and the id path 
value.
Remote attackers can manipulate the `index.php` file GET method request with the vulnerable ./pdirl path value to 
compromise 
client-side web application context.

Successful exploitation of the client-side cross site scripting web vulnerability results in session hijacking, 
client-side 
phishing, client-side unauthorized external redirects and client-side manipulation of the contact formular module 
context.


Vulnerable Module(s):
                                [+] .pdirl

Vulnerable File(s):
                                [+] index.php

Vulnerable Path:
                                [+] ../icons/
                                [+] ../icons/default
                                [+] ../template/
                                [+] ../template/default
                                [+] ../.pdirl/templates


Proof of Concept (PoC):
=======================
The client-side cross site scripting web vulnerabilities can be exploited by remote attackers without privileged web 
application user 
account but with low user interaction. For demonstration or to reproduce ...

Security Risk:
==============
1.1
The security risk of the client-side cross site scripting web vulnerabilities are estimated as medium.

1.2
The security risk of the client-side cross site request forgery web vulnerability is estimated as medium(-).

1.3
The security risk of the full path disclosure issue is estimated as low.
