Title source: llmExploitation Summary
EIP tracks 2 public exploits for CVE-2017-13209. PoCs published by Google Security Research, caofangkuai.
AI-analyzed exploit summary This exploit leverages a race condition in the Android hardware service manager to bypass SELinux access controls, allowing an attacker to replace critical system services. The PoC demonstrates hijacking the 'IBase' service by manipulating process PIDs during binder transactions.
Description
In the ServiceManager::add function in the hardware service manager, there is an insecure permissions check based on the PID of the caller which could allow an application or service to replace a HAL service with its own service. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 8.0, 8.1. Android ID: A-68217907.
