(Copy of the Homepage: https://itunes.apple.com/de/app/air-transfer/id521595136 ) Abstract: ========= The Vulnerability Laboratory Research Team discovered a local file include vulnerability in the mobile Air Transfer v1.2.0 app for the apple ipad & iphone. Report-Timeline: ================ 2013-02-14: Public Disclosure Status: ======== Published Affected Products: ================== Apple AppStore Product: Air Transfer Application - (iPad & iPhone) 1.2.0 Exploitation-Technique: ======================= Remote Severity: ========= High Details: ======== A local file include web vulnerability via POST request method is detected in the mobile WirelessFiles v1.1 app for the apple ipad & iphone. The vulnerability allows remote attackers via POST method to inject local app webserver folders to request unauthorized local webserver files. The vulnerbility is located in the upload file module of the webserver (http://192.168.0.10/) when processing to load a manipulated filename via POST. The execution of the injected path or file request will occur when the attacker is opening the generated links in the file dir listing. First the remote attacker drag&drop (copy) a manipulated link with system path or local files to request. He adds the local file request and in the secound step the attacker opens the generated link in the listing to execute the code out of the index module. Exploitation of the web vulnerability requires low privileged application user account without user interaction. Successful exploitation of the vulnerability results in unauthorized path or file access via local file or path include attack. Vulnerable Application(s): [+] Air Transfer v1.2.0 - ITunes or AppStore (Apple) Vulnerable Module(s): [+] File Upload Vulnerable Function(s): [+] Drag&Drop & Listing (Web Server) [Remote] Vulnerable Parameter(s): [+] name (Drop Web Addr Here) [+] filename (Drop Web Addr Here) Affected Module(s): [+] Air Transfer Filename Index - Listing Proof of Concept: ================= The local file include web vulnerability can be exploited by remote attackers without required user interaction and with privileged application user account. For demonstration or reproduce ... Input: (Upload) http://192.168.0.10:8080/Upload Example: http://[Server]:[PORT]/[Local File or Path Include] PoC: http://192.168.0.10:8080/var/mobile/Applications/2D31A1B7-6A58-42CE-A5B2-EB7307BE5B6F/AirScrap2%20Lite.app/note.png ../var/mobile/Applications/2D31A1B7-6A58-42CE-A5B2-EB7307BE5B6F/AirScrap2 Lite.app/note.png --- POST --- =-----------------------------19781325924485 Content-Disposition: form-data; name=``[Local File or Path Include]``; filename=``[Local File or Path Include].jpg`` Content-Type: image/jpeg ÿØÿà 192.168.0.10:8080 --- Manually steps to reproduce ... 1.

Open the air transfer file dir service application http://192.168.0.10:8080/ 5. Start your browser session tamper tool to manipulate the post request live 4. Use the Drag&Drop function to upload via http://192.168.0.10:8080/Upload and choose any random file 5. Submit the random picture and exchange the name and filename values (POST) with your local path or file request 7. Refresh the index listing of the main service http://192.168.0.10:8080 and open the generated link with your path/file request 8. The path or file will be loaded and is accessable 9. The application can be compromised by mobile webshell uploads and other malicious and persistent injected context 10. Successful reproduced ... done! Risk: ===== The security risk of the local file include web vulnerability is estimated as high(+).
