Background
OpenOCD is an on-chip JTAG debug solution designed for ARM and MIPS systems. It provides developers with the ability to debug and program microcontrollers and other embedded devices. OpenOCD allows for communication with the target device through various protocols, including JTAG, SWD, and others. However, a vulnerability has been discovered in OpenOCD that allows remote attackers to conduct cross-protocol scripting attacks.
Vulnerability Detail
The vulnerability in OpenOCD arises from its failure to block attempts to use HTTP POST requests for sending data to localhost. This oversight enables remote attackers to execute arbitrary commands by crafting a malicious website and tricking users into visiting it. By exploiting this vulnerability, an attacker can execute commands on the target system with the privileges of the user running OpenOCD. This can lead to unauthorized access, data theft, or further compromise of the affected system.
How To Fix

FAQ
OpenOCD is an on-chip JTAG debug solution used for debugging and programming microcontrollers and embedded devices.
A cross-protocol scripting attack occurs when an attacker leverages a vulnerability to execute malicious scripts across different protocols, such as using an HTTP POST request to exploit a JTAG debugging tool like OpenOCD.
An attacker can exploit this vulnerability by crafting a malicious website and tricking users into visiting it. The website would send specially crafted HTTP POST requests to localhost, which OpenOCD would process and execute arbitrary commands on the target system.
The consequences of this vulnerability include unauthorized access to the target system, data theft, and potential further compromise of the affected system.
Yes, a fix is available for this vulnerability. Users are advised to upgrade their OpenOCD package to version 0.5.0-1+deb7u1 or later.
