CVE-2023-2002 is a Linux kernel Bluetooth HCI socket vulnerability caused by a missing capability check. The missing authorization enforcement permits a low-privileged attacker to issue Bluetooth management commands that should require elevated capability authorization.

This repository contains a proof-of-concept (PoC) exploit for CVE-2023-2002, a vulnerability in the Linux kernel's Bluetooth subsystem. The vulnerability allows an unprivileged user to mark an HCI socket as 'trusted' by leveraging setuid programs (such as 'sudo') that perform ioctl calls on file descriptors. Once the socket is trusted, the user can send management commands, such as changing the power state of Bluetooth devices, which should normally require CAP_NET_ADMIN privileges. The repository structure includes: - A main README.md with a detailed vulnerability analysis and exploitation steps. - An 'exp' directory containing: - bt_power.c: The main exploit code, which creates a Bluetooth HCI socket, uses a fork/exec trick to gain the trusted flag, binds to the management channel, and sends a Set Powered command to the specified Bluetooth device. - bluetooth.h: Header file with Bluetooth protocol and management command definitions. - Makefile: For building the exploit binary. - README.md: Usage instructions for the exploit. The exploit is operational as a PoC and demonstrates the ability to change the power state of Bluetooth devices as an unprivileged user on vulnerable Linux systems. No remote or network endpoints are involved; the attack vector is local privilege escalation via manipulation of Bluetooth device management.
