Document Title: =============== pdirl PHP Directory Listing 1.0.4 - Cross Site Scripting Web Vulnerabilities References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=1130 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.) (Copy of the Vendor Homepage: http://pdirl.newroots.de/ ) 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.
