Vulnerability Note VU#311644

pd-admin contains cross-site scripting vulnerabilities

Original Release date: 15 Apr 2013 | Last revised: 15 Apr 2013

Overview

pd-admin, a web interface for users of hosting providers, is susceptible to cross-site scripting (XSS) vulnerabilities.

Description

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

pd-admin, contains cross-site scripting (XSS) vulnerabilities.

The vulnerability report provided by Thomas Roth states:

    Reflective cross-site scripting
    When pasting the string below into the 'Create new directory' textfield (found under 'WebFTP' -> 'Overview'), the error page will include the attacker supplied JavaScript code.

    "><script>alert("XSS");</script>

    Stored cross-site scripting
    When storing the string below as the body for an e-mail autoresponder, every time someone tries to change the text of the autoresponder, the attacker supplied JavaScript code will execute. By tricking a (higher privileged) support contact into looking at it, the attacker might be able to steal the support contact's session cookie.

    </textarea><script>alert("XSS");</script>

Impact

An attacker may be able to exploit the cross-site scripting vulnerability to result in information leakage, privilege escalation, and/or denial of service on the host computer.

Solution

Apply an Update
pd-admin 4.17 has been released to address these vulnerabilities.

Restrict access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS attacks since the attack comes as an HTTP request from a legitimate user's host. Restricting access would prevent an attacker from accessing the web interface using stolen credentials from a blocked network location.
