AI-analyzed exploit summary This repository contains a working PoC for CVE-2018-12633, an authentication bypass vulnerability in TP-Link TL-WR840N routers. The exploit manipulates the HTTP Referer header to bypass authentication and dump the router's encrypted configuration file, which can then be decrypted to extract sensitive information.
Description
An issue was discovered in the Linux kernel through 4.17.2. vbg_misc_device_ioctl() in drivers/virt/vboxguest/vboxguest_linux.c reads the same user data twice with copy_from_user. The header part of the user data is double-fetched, and a malicious user thread can tamper with the critical variables (hdr.size_in and hdr.size_out) in the header between the two fetches because of a race condition, leading to severe kernel errors, such as buffer over-accesses. This bug can cause a local denial of service and information leakage.
