Document Title: =============== PhotoSync Wifi & Bluetooth v1.0 - File Include Vulnerability References (Source): ==================== http://www.vulnerability-lab.com/get_content.php?id=1289 Release Date: ============= 2014-08-04 Vulnerability Laboratory ID (VL-ID): ==================================== 1289 Common Vulnerability Scoring System: ==================================== 6.8 Product & Service Introduction: =============================== PhotosSync - Wifi Bluetooth let you transfer photos from one iPhone, iPod Touch, iPad to another iPhone, iPod Touch, iPad, Mac and PC. - Wifi Transfer, support PhotosSync or most web browsers(safari, firefox, chrome, opera, IE) - Bluetooth Transfer, very useful when no wifi , no network available - Upload photos from Mac/PC to iPhone, iPad, iPod Touch (Wifi needed) - QRCode, scan QRCode to download photo, very convenient ( Copy of the Homepage: https://itunes.apple.com/ke/app/photossync-wifi-bluetooth/id570672848 ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Research Team discovered a local file include web vulnerability in the official PhotoSync Wifi&Bluetooth 1.0 iOS mobile application. Vulnerability Disclosure Timeline: ================================== 2014-08-04: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Haixia Liu Product: PhotoSync Wifi&Bluetooth - 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 PhotoSync Wifi&Bluetooth 1.0 iOS mobile 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 <code>filename</code> value of the <code>upload</code> module. Remote attackers are able to inject own files with malicious <code>filename</code> values in the <code>upload</code> POST method request to compromise the mobile web-application. The local file/path include execution occcurs in the index <code>file list</code> context next to the vulnerable <code>filename</code> item value. The attacker is able to inject the local malicious file request by usage of the available <code>wifi interface</code> (http://localhost:8000/) upload form. 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 6.8. Exploitation of the local file include web vulnerability requires no privileged web-application user account or 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): [+] PhotoSync Wifi&Bluetooth 1.0 Vulnerable Module(s): [+] upload Vulnerable Parameter(s): [+] filename Affected Module(s): [+] PhotoSync Images Dir Listing (http://localhost:8000/) Proof of Concept (PoC): ======================= The local file include web vulnerability can be exploited by local attackers without privileged application user account and without user interaction. For security demonstration or to reproduce follow the provided information and steps below to continue. PoC: http://localhost:8000/images/./[LOCAL FILE INCLUDE VULNERABILITY!] PoC: Index File Dir Listing (http://localhost:8000/) <script type="text/javascript"> function selectDivImage(div) { if (div.children[1].style.visibility == "hidden") { div.children[1].style.visibility = "visible"; } else { div.children[1].style.visibility = "hidden"; } } function saveImages() { var divs = document.getElementsByTagName('div'); for (var i = 0; i < divs.length; i++) { var div = divs[i]; if (div.children[1].style.visibility == "visible") { var str = div.children[0].src; if (str.indexOf("Video") != -1) { str = str.replace(".jpg", ".mov"); } window.open(str.replace("_thumbnail", "")); } } } function selectImages() { var divs = document.getElementsByTagName('div'); for (var i = 0; i < divs.length; i++) { divs[i].children[1].style.visibility = "visible"; } } function deselectImages() { var divs = document.getElementsByTagName('div'); for (var i = 0; i < divs.length; i++) { divs[i].children[1].style.visibility = "hidden"; } } </script> <span style="padding-left:50px"></span> <span style="color: blue; cursor: pointer;" onclick="deselectImages();">Deselect All</span> <span style="padding-left:5px"></span> <span style="color: blue; cursor: pointer;" onclick="selectImages();">Select All</span> <span style="padding-left:5px"></span> <span style="color: blue; cursor: pointer;" onclick="saveImages();">Save</span><br> <div onselectstart="return false;" onclick="selectDivImage(this);"> <img src="https://www.exploit-db.com/exploits/34303/[LOCAL FILE INCLUDE VULNERABILITY!].png" height="75" width="75"> <img src="https://www.exploit-db.com/exploits/34303/images/[LOCAL FILE INCLUDE VULNERABILITY!].png" style="position:absolute; left:2px; top:2px; visibility: hidden;" height="75" width="75"> </div> --- PoC Session Logs [POST] (LFI) --- Status: [OK] POST http://localhost:8000/ Load Flags[LOAD_DOCUMENT_URILOAD_INITIAL_DOCUMENT_URI] Gr��e des Inhalts[unknown] Mime Type[unknown] Request Header: Host[localhost:8000] User-Agent[Mozilla/5.0 (Windows NT 6.3; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0] Accept[text/html,application/xhtml +xml,application/xml;q=0.9,*/*;q=0.8] Accept-Language[de,en-US;q=0.7,en;q=0.3] Accept-Encoding[gzip, deflate] Referer[http://localhost:8000/] POST- Daten: POST_DATA[-----------------------------881789944691 Content-Disposition: form-data; name="file1"; filename="./[LOCAL FILE INCLUDE VULNERABILITY!].png" Content-Type: image/png Solution - Fix & Patch: ======================= The file include web vulnerability can be patched by a secure encode of the vulnerable file name value. Encode and filter also the vulnerable output in the images dir index listing file. Restrict the filename value input and filter the requests to prevent against further local file include attacks against the main directory listing service. Security Risk: ============== The security risk of the local file include web vulnerability in the upload module of the mobile application is estimated as high.
