A USB backdoor feature can be triggered by attaching a USB drive that contains specially crafted salia.ini files. The .ini file can contain several commands that could be exploited by an attacker to export or modify the device configuration, enable an SSH backdoor or perform other administrative actions. Ultimately, this backdoor also allows arbitrary execution of OS commands.
The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.
This weakness can lead to a wide variety of resultant weaknesses, depending on the behavior of the exposed method. It can apply to any number of technologies and approaches, such as ActiveX controls, Java functions, IOCTLs, and so on. The exposure can occur in a few different ways:
Identify all exposed functionality. Explicitly list all functionality that must be exposed to some user or set of users. Identify which functionality may be:
Ensure that the implemented code follows these expectations. This includes setting the appropriate access modifiers where applicable (public, private, protected, etc.) or not marking ActiveX controls safe-for-scripting.
