High
Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the official PhotoWIFI Lite or WIFI Photo and Files Transfer v1.0 iOS mobile web-application.
A file include web vulnerability allows remote attackers to unauthorized include local file/path requests or system specific path commands
to compromise the web-application or mobile device.
The local vulnerability is located in the `filename` value of the `Upload File` module. Remote attackers are able to inject own files with
malicious `filename` value in the upload POST method request to compromise the mobile web-application. The attack vector is persistent and
the request method to inject is POST. The local file/path include execution occcurs in the index file dir listing. The security risk of the
local file include web vulnerability is estimated as high(+) with a cvss (common vulnerability scoring system) count of 6.4(+)|(-)6.5.
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.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload File > Submit
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File Dir List (http://localhost:85***/)
1.2
An arbitrary file upload web vulnerability has been discovered in the official PhotoWIFI Lite or WIFI Photo and Files Transfer v1.0 iOS mobile web-application.
The arbitrary file upload issue allows remote attackers to upload files with multiple extensions to bypass the web-server or system validation.
The vulnerability is located in the `Upload File` > submit module. Remote attackers are able to upload a php or js web-shells by renaming
the file with multiple extensions to bypass the file restriction mechanism. The attacker uploads for example a web-shell with the following name
and extension `ptest.jpg.html.php.js.aspx.jpg`. After the upload the attacker needs to open the file with the path value in the web application.
He deletes the .jpg file extension and can access the application with elevated executable access rights. To access the file with elevated
executable access rights the attacker needs to implement the local raw upload path of the application. The security risk of the arbitrary file
upload web vulnerability is estimated as high(+) with a cvss (common vulnerability scoring system) count of 6.6(+)|(-)6.7.
Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privileged application user account with password.
Successful exploitation of the vulnerability results in unauthorized file access because of a compromise after the upload of web-shells.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload File > Submit
Vulnerable Parameter(s):
[+] filename (multiple extensions)
Affected Module(s):
[+] Index File Dir List (http://localhost:85***/)
1.3
A local command/path injection web vulnerability has been discovered in the official PhotoWIFI Lite or WIFI Photo and Files Transfer v1.0 iOS mobile web-application.
The vulnerability allows to inject local commands via vulnerable system values to compromise the apple mobile iOS application.
The vulnerability is located in the vulnerable `devicename` value of the wireless transfer app index header location module.
Local attackers with physical device access are able to manipulate the iOS `devicename` to compromise the affected header
location context in the file dir index list. The execution of the injected command/path request occurs in the all wifi
interface sites with implemented devicename in the header location. The request method to inject system specific commands via
the vulnerable devicename value is a local sync via (apple - ios) device.The security risk of the command/path inject
vulnerability is estimated as high(-) with a cvss (common vulnerability scoring system) count of 6.6(-).
Exploitation of the command/path inject vulnerability requires a local low privileged iOS device account with restricted access
and no direct user interaction. Successful exploitation of the vulnerability results unauthorized execution of system specific
commands or unauthorized path requests.
Request Method(s):
[+] [SYNC]
Vulnerable Parameter(s):
[+] devicename
Affected Module(s):
[+] Header Location - Index File Dir List (http://localhost:85***/)
Proof of Concept (PoC):
