Affected Product(s): ==================== bdtask Product: Isshue Shopping Cart v3.5 - eCommerce (Web-Application) Vulnerability Disclosure Timeline: ================================== 2021-08-23: Researcher Notification & Coordination (Security Researcher) 2021-08-24: Vendor Notification (Security Department) 2021-**-**: Vendor Response/Feedback (Security Department) 2021-**-**: Vendor Fix/Patch (Service Developer Team) 2021-**-**: Security Acknowledgements (Security Department) 2021-10-22: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Medium Authentication Type: ==================== Restricted Authentication (Moderator Privileges) User Interaction: ================= Medium User Interaction Disclosure Type: ================ Responsible Disclosure Technical Details & Description: ================================ A persistent input validation web vulnerability has been discovered in the official Isshue eCommerce Shopping Cart v3.5 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. A input validation web vulnerability has been discovered in the title input fields in `new invoice`, `customer` & `stock` modules. The `title` input and parameter allows to inject own malicious script code with persistent attack vector. The content of the input and parameter is insecure validated, thus allows remote attackers with privileged user accounts (manager/keeper/admin) to inject own malformed script code that executes on preview. The request method to inject is post and the attack vector is persistent on the application-side. 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 Method(s): [+] POST Vulnerable Module(s): [+] Edit Title Vulnerable Input(s): [+] Title Vulnerable Parameter(s): [+] title Affected Module(s): [+] stock [+] customer [+] invoice Proof of Concept (PoC): ======================= The persistent input validation web vulnerability can be exploited by remote attackers with keeper account and with low user interaction.
