Multiple Vulnerabilities in BHU WiFi “uRouter”
A Wonderful (and !Secure) Router from China The BHU WiFi uRouter, manufactured and sold in China, looks great – and it contains multiple critical vulnerabilities. An unauthenticated attacker could bypass authentication, access sensitive information stored in its system logs, and in the worst case, execute OS commands on the router with root privileges. In addition, the uRouter ships with hidden users, SSH enabled by default and a hardcoded root password…and injects a third-party JavaScript file into all users’ HTTP traffic. In this blog post, we cover the main security issues…
Securing the Connected Car: Commonalities in Vehicle Vulnerabilities
With the Connected Car becoming commonplace in the market, vehicle cybersecurity grows more important by the year. At the forefront of this growing area of security research, IOActive has amassed real-world vulnerability data illustrating the general issues and potential solutions to the cybersecurity issues facing today’s vehicles. This paper explains the differences in testing methodologies, with recommendations on the most appropriate methods for testing connected vehicle systems. Detailed findings follow, including the impact, likelihood, overall risk, and remediation of vulnerabilities IOActive consultants have discovered over the course of thousands of…
Multiple Vulnerabilities in D-Link DCS-5009L IP Camera
The D-Link DCS-5009L IP Camera can be used to remotely monitor your home. It can be accessed via the D-Link Cloud or configured to upload recordings to an FTP server, as well as send notifications by email. The DCS-5009L can rotate and tilt, and has night vision and movement detection. IOActive has identified four high-risk and two low-risk vulnerabilities in the D-Link DCS-5009L IP Camera. An attacker could exploit these issues to fully compromise the confidentiality, integrity, and availability of the product.
Assessing and Exploiting XML Schema’s Vulnerabilities
Specifications for XML and XML schemas include multiple security flaws. At the same time, these specifications provide the tools required to protect XML applications. This provides a complex scenario for developers, and a fun environment for hackers. Even though we use XML schemas to define the security of XML documents, we also use them to perform a variety of attacks: file retrieval, server side request forgery, port scanning, or brute forcing. This talk will analyze how to infer new attack vectors by analyzing the current vulnerabilities, and how it is…
Inside the IOActive Silicon Lab: Interpreting Images
In the post “Reading CMOS layout,” we discussed understanding CMOS layout in order to reverse-engineer photographs of a circuit to a transistor-level schematic. This was all well and good, but I glossed over an important (and often overlooked) part of the process: using the photos to observe and understand the circuit’s actual geometry. Optical Microscopy Let’s start with brightfield optical microscope imagery. (Darkfield microscopy is rarely used for semiconductor work.) Although reading lower metal layers on modern deep-submicron processes does usually require electron microscopy, optical microscopes still have…
Got 15 minutes to kill? Why not root your Christmas gift?
TP-LINK NC200 and NC220 Cloud IP Cameras, which promise to let consumers “see there, when you can’t be there,” are vulnerable to an OS command injection in the PPPoE username and password settings. An attacker can leverage this weakness to get a remote shell with root privileges. The cameras are being marketed for surveillance, baby monitoring, pet monitoring, and monitoring of seniors. This blog post provides a 101 introduction to embedded hacking and covers how to extract and analyze firmware to look for common low-hanging fruit in security. This post…
Authenticated OS Command Injection on TP-LINK Cloud Cameras
An attacker with Administrator (admin) access to the administrative web panel of a TP-LINK Cloud Camera can gain root access to the device, fully compromising its confidentiality, integrity, and availability.
Inside the IOActive Silicon Lab: Reading CMOS layout
Ever wondered what happens inside the IOActive silicon lab? For the next few weeks we’ll be posting a series of blogs that highlight some of the equipment, tools, attacks, and all around interesting stuff that we do there. We’ll start off with Andrew Zonenberg explaining the basics of CMOS layout. Basics of CMOS Layout When describing layout, this series will use a simplified variant of Mead & Conway’s color scheme, which hides some of the complexity required for manufacturing. Material Color P doping N doping Polysilicon…
Remotely Disabling a Wireless Burglar Alarm
Countless movies feature hackers remotely turning off security systems in order to infiltrate buildings without being noticed. But how realistic are these depictions? Time to find out. Today we’re releasing information on a critical security vulnerability in a wireless home security system from SimpliSafe. This system consists of two core components, a keypad and a base station. These may be combined with a wide array of sensors ranging from smoke detectors to magnet switches to motion detectors to create a complete home security system. The system is marketed…
SimpliSafe Alarm System Replay Attack
The radio interface for the SimpliSafe home burglar/fire alarm systems is not encrypted and does not use “rolling codes,” nonces, two-way handshakes, or other techniques to prevent transmissions from being recorded and reused. An attacker who is able to intercept the radio signals between the keypad and base station can record and re-play the signal in order to turn off the alarm at a time of his choice in the future.
