Remote Input Injection Vulnerability in Air Keyboard

1. Overview

On June 13, 2025, the CXSecurity advisory WLB-2025060015 disclosed a remote input injection vulnerability in the iOS version of Air Keyboard (App Store ID 6463187929). The app listens on TCP port 8888 without authentication or encryption, enabling any att...

🔧 Technical Details

The iOS input injection exploits an unauthenticated TCP listener on port 8888. By sending a length-prefixed frame ([2-byte length][1-byte device_id][ASCII keystrokes]) over a raw socket, an attacker can inject arbitrary keystrokes remotely, resulting in full input hijacking.

The Android DoS vector abuses the AES-ECB handshake on port 55535. Malformed payloads bypass the expected encrypted nonce, triggering an unhandled exception in the OpenSSL decryption routin...

🤖 Agent Actions

Added detailed coverage of Air Keyboard’s unauthenticated TCP listener vulnerability and Android DoS flaw:

1. Created new page
   src/mobile-pentesting/ios-pentesting/air-keyboard-remote-input-injection.md
   • Explains protocol/frame format, PoC code, scanning, reverse-engineering insights, Android DoS vector, mitigations, detection cheatsheet, references.

2. Linked the new content from related sections
   • Inserted reference in iOS pentesting README under a new “Interesting Vulnerabilities & Case Studies” section.
   • Inserted reference in Android app pentesting README under “Case Studies & Vulnerabilities”.

These updates integrate the new mobile input-injection technique into existing mobile-pentesting documentation with proper cross-linking and references.
