Details:

========
|
||
1.1
|
||
A local file include and arbitrary file upload web vulnerability is detected in the Olive File Manager v1.0.1 application (Apple iOS - iPad & iPhone).
|
||
The vulnerability allows remote attackers to upload files via POST method with multiple extensions to unauthorized access them on application-side of the service.
|
||
|
||
The vulnerability is located in the file upload/add module of the web-server (http://localhost:8797/) when processing to request
|
||
a manipulated filename via POST. The injected file will be accessable via the index listing module of the web application.
|
||
|
||
Remote attackers can exchange the filename with a double or tripple extension bia POST method to bypass the upload validation and filter process.
|
||
After the upload the attacker access the file with one extension and exchange it with the other one to execute for example php codes.
|
||
|
||
A persistent script code injection is detected in the filename parameter. Attackers can tamper the request and exchange the file name with
|
||
persistent malicious script code or tags. The code will be executed in the main index site when processing to list the object (file) items.
|
||
Attackers are also able to inject persistent code with local frame requests to unauthorized access application data/apps or restricted
|
||
application information. The execution of the persistent code also occurs when an application user is processing to refresh, update or delete
|
||
the malicious web context.
|
||
|
||
Exploitation of the vulnerability requires no user interaction and also without privilege application user account (no password standard).
|
||
Successful exploitation of the vulnerability results in unauthorized path or file access via local file include or arbitrary file upload.
|
||
|
||
Vulnerable Application(s):
|
||
[+] Olive File Manager v1.0.1 - ITunes or AppStore (Apple)
|
||
|
||
Vulnerable Module(s):
|
||
[+] File Upload (Web Server) [Remote]
|
||
|
||
Vulnerable File(s):
|
||
[+] AirDriveAction_file_add
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename
|
||
|
||
Affected Module(s):
|
||
[+] Application Index File Listing (http://localhost:8797/)
|
||
|
||
|
||
|
||
1.2
|
||
A persistent input validation web vulnerability is detected in the Olive File Manager v1.0.1 application (Apple iOS - iPad & iPhone).
|
||
The bug allows an attacker (remote) to implement/inject malicious script code on the application side (persistent) of the app.
|
||
|
||
The vulnerability is located in the index file dir listing module of the web-server (http://localhost:8797/) when processing to
|
||
display via POST request method injected manipulated `folder names`. The persistent script code will be executed in the main
|
||
index file dir listing module when the service lists the new malicious injected foldername as item.
|
||
|
||
Exploitation of the persistent web vulnerability requires low or medium user interaction without application user account.
|
||
Successful exploitation of the vulnerability can lead to persistent session hijacking (customers), account steal via persistent
|
||
web attacks, persistent phishing or stable (persistent) certificate mail notification context manipulation.
|
||
|
||
Vulnerable Application(s):
|
||
[+] Olive File Manager v1.0.1 - ITunes or AppStore (Apple)
|
||
|
||
Vulnerable Module(s):
|
||
[+] Add Folder
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] foldername
|
||
|
||
Affected Module(s):
|
||
[+] Index Folder Listing (http://localhost:8797/)
|
||
|
||
|
||
Proof of Concept:
|
||
=================
|
||
1.1
|
||
The file include and arbitrary file upload vulnerability can be exploited by remote attackers without privilege application user account
|
||
and without required user interaction. For demonstration or reproduce ...
