Vulnerability Disclosure Timeline: ================================== 2014-09-22: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Golden Soft Product: Foto Überträger - iOS Mobile Web Application 3.0 Exploitation Technique: ======================= Local Severity Level: =============== High Technical Details & Description: ================================ A local file include web vulnerability has been discovered in the official Briefcase Pro v4.0 iOS mobile wifi 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 and albumname` values of the `uploadPhotoPost` module. Remote attackers are able to inject own files with malicious `filename or albumname` values in the `uploadPhotoPost` POST method request to compromise the mobile web-application. The local file/path include execution occcurs in the index dir listing of the wifi interface context. The attacker is able to inject the local file include request by usage of the `wifi interface` in connection with the vulnerable upload request. Remote attackers are also able to exploit the filename/albumname 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 6.3. Exploitation of the local file include web 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 connected device component compromise. Request Method(s): [+] [POST] Vulnerable Module(s): [+] uploadPhotoPost Vulnerable Parameter(s): [+] filename & albumname Affected Module(s): [+] Index Path Dir Listing (http://localhost/) Proof of Concept (PoC): ======================= The local file include web vulnerability can be exploited by local wifi attackers in the network without privileged application user account or user interaction.
