LG On-Screen Phone (OSP) versions prior to 4.3.010 contain an authorization bypass vulnerability. Remote attackers can send specially crafted requests to the OSP service, allowing them to bypass normal authorization mechanisms and potentially gain unauthorized access to the device or its functions.

This repository provides a proof-of-concept (PoC) exploit for CVE-2014-8757, an authentication bypass vulnerability in LG's On Screen Phone (OSP) application (v4.3.009 and older) for Android smartphones. The exploit consists of two Perl scripts: 1. **osp-discovery.pl**: Listens for UDP discovery broadcast messages from the official LG OSP application and responds, making the application believe a phone running OSP is available locally. It operates on UDP port 19528. 2. **osp-proxy.pl**: Acts as a proxy, accepting incoming TCP connections from the OSP client (typically running on a PC) on port 8382. It then connects to the real LG phone's OSP service (also on port 8382) and relays traffic. The script specifically skips the authentication message, exploiting the vulnerability that allows further commands to be sent without user confirmation on the phone. The README.md provides detailed background, technical explanation, and usage instructions. The exploit enables an attacker on the same local network to gain full control over a vulnerable LG smartphone without user consent, by bypassing the OSP authentication dialog. No payload is included beyond the proxying and bypass logic, making this a PoC-level exploit. The repository is well-structured, with clear separation between discovery and exploitation components.
