Official description
The Quantenna Wi-Fi chipset ships with a local control script, transmit_file, that is vulnerable to command injection. This is an instance of CWE-88, "Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')," and is estimated as a CVSS 7.7 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). This issue affects Quantenna Wi-Fi chipset through version 8.0.0.28 of the latest SDK, and appears to be unpatched at the time of this CVE record's first publishing, though the vendor has released a best practices guide for implementors of this chipset.

The underlying weakness: Improper Neutralization of Argument Delimiters in a Command
The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string.
How developers prevent this class of flaw
- Understand all the potential areas where untrusted inputs can enter your product: parameters or arguments, cookies, anything read from the network, environment variables, request headers as well as content, URL components, e-mail, files, databases, and any external systems that provide data to the application. Perform input validation at well-defined interfaces.
- Directly convert your input type into the expected data type, such as using a conversion function that translates a string into a number. After converting to the expected data type, ensure that the input's values fall within the expected range of allowable values and that multi-field consistencies are maintained.
- When exchanging data between components, ensure that both components are using the same character encoding. Ensure that the proper encoding is applied at each interface. Explicitly set the encoding you are using whenever the protocol allows you to do so.
