Technical Details & Description:
================================
A persistent cross site web vulnerability has been discovered in the Ultimate POS v4.4 erp stock management 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 persistent validation web vulnerability is located in the name parameter of the add products module.
Remote attackers with privileges as vendor to add products are able to inject own malicious script codes.
The request method to inject is post and the attack vector is persistent. Injects are possible via edit
or by a new create of a product.
Successful exploitation of the vulnerabilities results in session hijacking, persistent phishing attacks,
persistent external redirects to malicious source and persistent manipulation of affected application modules.
Request Method(s):
[+] POST
Vulnerable Module(s):
[+] Products (Add)
Vulnerable Input(s):
[+] Product Name
Vulnerable Parameter(s):
[+] name
Affected Module(s):
[+] Products List
Proof of Concept (PoC):
=======================
The persistent web vulnerability can be exploited by remote attackers with privileged application account and with low user interaction.
For security demonstration or to reproduce the cross site web vulnerability follow the provided information and steps below to continue.
