Description Preview

An authentication bypass vulnerability has been identified in the Swift Sensors Gateway SG3-1010 device's password generation functionality. This vulnerability allows an attacker to bypass authentication mechanisms by sending specially-crafted network requests to the device. Once authentication is bypassed, the attacker can achieve remote code execution on the affected system. The vulnerability can be triggered by sending a specific sequence of network requests to the device, potentially giving an attacker complete control over the gateway.

Overview

The Swift Sensors Gateway SG3-1010 contains a critical vulnerability in its device password generation functionality. This authentication bypass vulnerability (CVE-2021-40422) allows remote attackers to execute arbitrary code on the affected system without requiring valid credentials. The gateway device, which is typically used in IoT sensor networks to collect and transmit data, can be completely compromised through this vulnerability. The attack vector involves sending specially-crafted network requests in a specific sequence to exploit the flawed password generation mechanism. Once exploited, an attacker could gain unauthorized access to the gateway and potentially to the connected sensor network, compromising the confidentiality, integrity, and availability of the system.

Remediation

To mitigate this vulnerability, system administrators should:

  1. Update the Swift Sensors Gateway SG3-1010 firmware to the latest version as provided by the manufacturer.
  2. If updates are not immediately available, consider implementing network segmentation to restrict access to the gateway device.
  3. Monitor network traffic to and from the gateway for suspicious activities.
  4. Implement strong network access controls to limit who can communicate with the gateway.
  5. Consider placing the gateway behind a firewall configured to filter potentially malicious requests.
  6. Contact Swift Sensors support for specific guidance related to this vulnerability.
  7. Perform a security assessment of your IoT environment to identify any signs of compromise.
