AirPhoto Product: PhotoWebsite - iOS Mobile Web Application 3.1
A local file include web vulnerability has been discovered in the official PhotoWebsite v3.1 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 `mDirNameList` and `mDirUrlList` values of the `airphotos.ma - upload` module. Remote attackers are able to inject own files with malicious `mDirNameList` values in the `upload.action` sync request to compromise the mobile web-application. The local file/path include execution occcurs in the index file dir listing of the wifi interface. The attacker is able to inject the local file include request by usage of the `wifi interface` in connection with the vulnerable upload service module.
Remote attackers are also able to exploit the `mDirNameList` and `mDirUrlList` validation issue in combination with persistent injected script codes to execute unique local malicious attack requests. The attack vector is located on the application-side of the wifi service and the request method to inject is POST (upload) or Sync(device). To exploit the bug it is required to use the local device > wifi sync or (remote) the wifi gui.
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 vulnerability requires no user interaction or privileged web-application user account. Successful exploitation of the local file include web vulnerability results in mobile application or device compromise.
Request Method(s): [+] Sync
Vulnerable Module(s): [+] upload
Vulnerable File(s): [+] airphotos.ma
Vulnerable Parameter(s): [+] mDirNameList [+] mDirUrlList
Affected Module(s): [+] File Dir Index
The local file include web vulnerability can be exploited by local attackers without privileged application user account or user interaction. For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.
The vulnerability can be patched by a secure parse and encode of the vulnerable `mDirNameList` and `mDirUrlList` values. Restrict the input for folder and album names on sync and disallow special chars. Encode the file dir index list that shows the malicious context without secure parse to prevent further file include or request injection attacks.
The security risk of the local file include web vulnerability in the photowebsite wifi app is estimated as high. (CVSS 6.6)
