Vulnerability Disclosure Timeline: ================================== 2014-09-08: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Jiajun Kuang Product: Photorange - iOS Mobile Web Application 1.0 Exploitation Technique: ======================= Local Severity Level: =============== High Technical Details & Description: ================================ A local file include web vulnerability has been discovered in the official Photorange v1.0 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 `filename` value of the `add file` module. Remote attackers are able to inject own files with malicious `filename` values in the `sync` device POST method request to compromise the mobile web-application. The local file/path include execution occcurs in the file dir index web interface through the download path 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 via sync. Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute different local malicious attack requests. The attack vector is on the application-side of the wifi service and the request method to inject is POST via Sync. 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 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): [+] [Sync] [POST] Vulnerable Parameter(s): [+] filename Affected Module(s): [+] Index File Dir Listing (Web Interface - http://localhost:9900/ ) Proof of Concept (PoC): ======================= 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.

Filter and restrict the input to prevent further executions. Encode also the output name value listing in the index file dir module. Security Risk: ============== The security risk of the local file include web vulnerability in the filename value of the mobile application is estimated as high.
