Official description

KERUI HD 3MP 1080P Tuya Camera 1.0.4 has a command injection vulnerability in the module that connects to the local network via a QR code. This vulnerability allows an attacker to create a custom, unauthenticated QR code and abuse one of the parameters, either SSID or PASSWORD, in the JSON data contained within the QR code. By that, the attacker can execute arbitrary code on the camera.

The underlying weakness: Improper Neutralization of Special Elements used in a Command

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How developers prevent this class of flaw

  • If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • If possible, ensure that all external commands called from the program are statically created.
  • Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
