Technical Details & Description:
================================
Multiple persistent input validation web vulnerabilities has been discovered in the WireShare v1.9.1 for apple iOS.
A persistent input validation web vulnerability allows remote attackers to inject own malicious script codes on the
application-side (persistent) of the affected application web-server.
The vulnerability is located in the add `New Folder` input field. The vulnerability allows remote attackers to inject
own malicious script codes on the application-side of the index path/folder listing. The script code execute occurs
in the index path/folder listing with the vulnerable foldername parameter. The inject can be done local by the device
via add folder function or by remote inject via web-interface. The second execute occurs when the user is requesting
to delete the malicious injected script code entry of the folder list. The security risk of the persistent input
validation web vulnerability in the foldername value is estimated as high(-) with a cvss (common vulnerability scoring
system) count of 6.4(+)|(-)6.5.
Exploitation of the persistent script code inject vulnerability via POST method request requires low user interaction
and no privileged web-interface user account. In the default settings is auth of the web-server deactivated and blank.
Request Method(s):
[+] POST
Vulnerable Module(s):
[+] New Folder (fileListContainer)
Vulnerable Module(s):
[+] folder [name value] (targetItem)
Affected Module(s):
[+] Folder Index List
Proof of Concept (PoC):
=======================
The persistent input validation web vulnerability can be exploited by local attackers with physical device access or
by remote attackers without privileged application user account and low user interaction. For security demonstration
or to reproduce the vulnerability follow the information and steps below.
