Foxboro FBM203 P0914SV Avoiding Code Injection Controller

The best way to avoid code FBM203  is through design. If you can use a language that will never have vulnerabilities, then this is best because your code is immune to all attacks during construction; Alternatively, you can design code to prohibit interfaces that may cause these issues.

Unfortunately, in embedded systems, these choices are not always feasible. Even though C is a dangerous language full of vulnerabilities, it is still the preferred language for many organizational structures. Given this, developers should be aware of other methods to avoid code injection.

Two golden FBM203  to follow to prevent code injection vulnerabilities:

·If you can avoid it, try not to compile data like code;

·If you are unable to avoid it, please make sure to verify if the data is good before using it.

To avoid loopholes in format strings, the first of these rules is the most appropriate; You can write the following code:

Printf (“% s”, str);

In this way, the content of FBM203  is only considered as data. This is the least brainy way, as long as you can find all the places where this kind of modification should be made. But this can be tricky for large programs, especially for third-party code libraries.
