Physical and Authentication Bypass in Diebold Opteva ATM

Historically, ATMs have been designed without privileged separation between the safe and the internal operating system. In an attempt to address this security concern, Diebold developed the AFD platform. The Opteva line of ATMs with the AFD platform contain an upper cabinet for the operating system and a lower cabinet for the safe, each with its own authentication requirements. Using reverse engineering and protocol analysis, IOActive found a critical vulnerability in the tested version of the Opteva ATM with the AFD platform. Despite its separation of privilege and authentication requirements,…

Secure Messaging Application Vulnerabilities Identified

IOActive security researchers tested versions 1.4.2 for Windows and OS X and 4.0.4 for Android, of the Confide messaging application by reverse engineering the published application, observing its behavior, and interacting with the public API. During the evaluation, multiple security vulnerabilities of varying severities were identified, with corresponding attacker exploitation risks ranging from account impersonation and message tampering, to exposing user contact details and hijacking accounts. The issues were reported to the vendor through responsible disclosure and many, including those identified as being critical, were subsequently addressed and resolved quickly…

Multiple Vulnerabilities in BHU WiFi “uRouter”

The BHU WiFi uRouter, manufactured and sold in China, 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. IOActive has identified seven medium to critical risk vulnerabilities in the product. An attacker could exploit these issues to fully compromise the…

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.

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.

Lenovo TVSUkernel Escalation of Privileges

The Lenovo System Update allows least-privileged users to perform system updates. To do this, System Update includes the System Update service (SUService.exe). This service runs as the privileged SYSTEM user, creates a temporary user account with Administrator privileges, and starts a GUI application (Tvsukernel.exe) with the new Administrator account. Once the application is closed, the temporary Administrator account is appropriately deleted. However the GUI application contains links to online support and privacy help topics, which, when clicked, start a web browser instance under the temporary Administrator account to display the…
