Technical Details & Description:
|
||
================================
|
||
A local file include web vulnerability has been discovered in the official Privacy Pro v1.2 iOS mobile web-application.
|
||
The local file include web vulnerability allows remote attackers to unauthorized include local file/path requests or system
|
||
specific path commands to compromise the mobile web-application.
|
||
|
||
The web vulnerability is located in the `filename` value of the `upload` module. Remote attackers are able to inject own files with
|
||
malicious `filename` values in the `upload` POST method request to compromise the mobile web-application. The local file/path include
|
||
execution occcurs not like regular in the index list but inside of the upload formular message filename context. The attacker is able
|
||
to inject the local file include request by usage of the `wifi interface`. The affected service inside of the application is only the
|
||
privacy manager `wifi revover data` module. (localhost:56380 -restore)
|
||
|
||
Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute
|
||
different local malicious attacks requests. The attack vector is on the application-side of the wifi service and the request method to
|
||
inject is POST.
|
||
|
||
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
|
||
count of 6.6. Exploitation of the local file include web vulnerability requires no user interaction but a privileged web-application
|
||
user account with low user auth. Successful exploitation of the local file include web vulnerability results in mobile application or
|
||
connected device component compromise.
