Document Title: =============== Secure Item Hub v1.0 iOS - Multiple Web Vulnerabilities References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=1682 Release Date: ============= 2016-01-27 Vulnerability Laboratory ID (VL-ID): ==================================== 1682 Common Vulnerability Scoring System: ==================================== 7.3 Product & Service Introduction: =============================== Transfer files to and from any computer connected to the same WiFi network as your iPhone or iPad using just a web browser! Just drag and drop files into the browser (requires a current version of Chrome, Firefox or Safari) and watch the files appear on your device. You can also connect to other iOS devices that have the Secure Item Hub app and transfer files directly between devices!

Vulnerability Disclosure Timeline: ================================== 2016-01-27: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Pinfolio LLC Product: Secure Item Hub - WiFi File Sharing 1.0 Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ 1.1 An arbitrary file upload web vulnerability has been discovered in the Secure Item Hub - WiFi File Sharing mobile iOS wifi web-application. The arbitrary file upload 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 `Upload` module. Remote attackers are able to inject own files with malicious `filename` values in the `Upload` POST method request to compromise the mobile web-application. The local file/path include execution occcurs in the index file dir listing and sub folders of the wifi interface. The attacker is able to inject the lfi payload by usage of the wifi interface or the local file sync function. The attacker can also attach multiple file extensions to bypass the web-server file validation to execute a malicious web-shell finally. Remote attackers can exchange the filename with a double or tripple extension via POST method to bypass the upload validation and filter process. After the upload the attacker access the file with one extension and exchange it with the other one to execute for example own php codes. Attackers are also able to exploit the filename issue in combination with persistent injected script code to execute different malicious attack requests. The attack vector is located on the application-side of the wifi service and the request method to inject is POST. The security risk of the local file include vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 8.7. Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privileged web-application user account. Successful exploitation of the arbitrary file upload vulnerability results in mobile application compromise or connected device component compromise. Request Method(s): [+] [POST] Vulnerable Module(s): [+] Upload [+] Rename Vulnerable Parameter(s): [+] filename [+] pairs Affected Module(s): [+] Index File Dir Listing (http://localhost:8000/) 1.2 A local command/path injection web vulnerabilities has been discovered in the official Secure Item Hub - WiFi File Sharing mobile iOS wifi web-application. The vulnerability allows attackers to inject local commands via vulnerable system values to compromise the apple mobile iOS application. The vulnerability is located in the vulnerable `devicename` value that becomes visible in the `file dir (index)` module. Local attackers are able to inject own malicious system specific commands or path value requests in the vulnerable `devicename` value. The execution of the local command inject occurs in the `index` module of the mobile application. The attacker is able to manipulate the header name information of the application by preparing to change the local devicename. The encoding of the vulnerable values in the index header module is broken. The attack vector is on the application-side and the injection requires physical device access or a local low privileged user account. Local 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 security risk of the local command/path inject vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 6.1. Exploitation of the command/path inject vulnerability requires a low privileged iOS device account with restricted access and no user interaction. Successful exploitation of the vulnerability results in unauthorized execution of system specific commands and unauthorized path value requests to compromise the mobile iOS application or the connected device components. Request Method(s): [+] [SYNC] Vulnerable Module(s): [+] Header Location - Web Application Vulnerable Parameter(s): [+] devicename (HierarchyText) Affected Module(s): [+] Index File Dir Listing (http://localhost:8000/) 1.3 A persistent input validation web vulnerability has been discovered in the official Secure Item Hub - WiFi File Sharing mobile iOS wifi web-application. The vulnerability allows remote attacker to inject malicious persistent script codes to the application-side of the mobile application. The vulnerability is located in the path and name (class) values of the `New Folder` and `NewTextFile` modules. The request method to inject is POST and the attack vector is located on the application-side of the mobile app. Remote attackers are able to inject via POST own malicious script codes to compromise the wifi web-application index file dir listing. The validation and encoding of the `New Folder` and `NewTextFile` modules are broken and allows to inject malicious persistent script codes. The security risk of the application-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.6. Exploitation of the application-side web vulnerability requires no privileged web-application user account and only low or medium user interaction. Successful exploitation of the vulnerabilities results in persistent phishing, session hijacking, persistent external redirect to malicious sources and application-side manipulation of affected or connected module context. Request Method(s): [+] [POST] Vulnerable Module(s): [+] NewTextFile [+] New Folder Vulnerable Parameter(s): [+] path [+] name (class) Affected Module(s): [+] Index File Dir Listing (http://localhost:8000/) Proof of Concept (PoC): ======================= 1.1 The arbitrary file upload web vulnerability can be exploited by remote attackers without privileged web-application user account or user interaction.
