You can also share your device information with any one. (Copy of the Vendor Homepage: https://itunes.apple.com/de/app/my-device-udid/id504520659 ) Abstract Advisory Information: ============================== The Vulnerability Laboratory Research Team discovered application-side validation vulnerability in the official UDID v1.0 iOS mobile web-application. Vulnerability Disclosure Timeline: ================================== 2015-09-22: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Hiteshi Technologies Product: UDID+ - iOS Mobile Web Application 1.0 Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ An application-side input validation web vulnerability has been discovered in the official UDID v1.0 iOS mobile web-application. The security web vulnerability allows to inject malicious script codes to the application-side of the vulnerable iOS mobile app. The vulnerability is located in the `Send UDID via Email` encoding. The application encodes the input of the device cell name with wrong conditions. Thus results in an application-side script code execution issue in the Send UDID via Email module. The attackers changes by restricted physical device access the device cell name to compromise the application output in the Send UDID via Email module. The security risk of the application-side input web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.6. Exploitation of the persistent web vulnerability requires a low privilege ios device account with restricted access and no user interaction. Successful exploitation of the vulnerabilities results in persistent phishing mails, session hijacking, persistent external redirect to malicious sources and application-side manipulation of affected or connected module context. Vulnerable Module(s) [+] Send UDID via Email Vulnerable Parameter(s) [+] device cell name (cid) Affected Module(s) [+] UDID Device Information (Mail) Proof of Concept (PoC): ======================= The application-side mail encoding web vulnerability can be exploited by local attackers with restricted physical device access without user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue. Manual steps to reproduce the vulnerability ... 1. Change the cid of the ios device via settings to a script code payload (test) 2. Open the vulnerable application 3. Click the Send UDID via Email button 4. Push the email button 5. The function includes the device values with wrong encoding to the email 6. Successful reproduce of the vulnerability! PoC: UDID.html
