Vulnerabilities Targeting InfiRay Thermal Cameras May Result in Industrial Process Hacking

Austrian cybersecurity organization SEC Consult found a series of vulnerabilities impacting Infiray IRAY-A8Z3 thermal cameras in February 2021.

The consulting organization disclosed the facts of the vulnerabilities in an advisory on Tuesday, stating they were a immediate consequence of insecure coding practices, insecure configuration and outdated software program factors within just the embedded firmware

SEC Consult also mentioned it uncovered several attack vectors that will final result in remote code execution (RCE).

For context, InfiRay is a China-based producer of optical elements, notably infrared and thermal imaging solutions. Its solutions are presently bought in 89 international locations and locations all around the world.

Since of the wide arrive at of its solutions, the discovered flaws could likely act as an entry place into industrial command systems (ICS) and supervisory command and info acquisition (SCADA) networks.

In phrases of critical vulnerabilities affecting the Infiray IRAY-A8Z3 cameras, SEC Talk to mentioned 5. The initial refers to the hardcoded qualifications for the camera’s web software. 

“As these accounts cannot be deactivated or change their passwords, they are regarded to be backdoor accounts.”

Secondly, the company mentioned the cameras’ web server interface incorporates an endpoint that can execute arbitrary commands by manipulating the “cmd_string” URL parameter, thus enabling user login employing a single of the aforementioned backdoor accounts.

The third issue refers to a opportunity buffer overflow attack that could be executed by calling strcpy() without checking the string duration initial.

Fourthly, the camera reportedly features a shell via a telnet connection. 

“The root person does not involve a password for each default. So, anyone on the neighborhood network can execute arbitrary instructions as root on the digicam.”

Eventually, SEC Talk to said the cameras have multiple outdated computer software factors that contains vulnerabilities that had been found making use of the IoT Inspector (OneKey) firmware analysis system.  

The security firm contacted InfiRay various periods in the course of its investigation, sending them a draft of the advisory in April 2021, but the vendor by no means responded to its requests.

Because of this, SEC Talk to warned it was unaware whether or not the vendor experienced patched the affected programs or not.

“The seller was unresponsive all through the disclosure procedure. Therefore it is unclear whether patches are out there. Buyers are urged to approach their vendor get in touch with and ask for security opinions and updates.”
