Micro-Learning Topic: Code injection (Detected by phrase)

Matched on "Code injection"

What is this? (2min video)

Code injection happens when an application insecurely accepts input that is subsequently used in a dynamic code evaluation call. If insufficient validation or sanitisation is performed on the input, specially crafted inputs may be able to alter the syntax of the evaluated code and thus alter execution. In a worst case scenario, an attacker could run arbitrary code in the server context and thus perform almost any action on the application server.
