Micro-Learning Topic: OS command injection (Detected by phrase)

Matched on "OS Command Injection"

What is this? (2min video)

In many situations, applications will rely on OS provided functions, scripts, macros and utilities instead of reimplementing them in code. While functions would typically be accessed through a native interface library, the remaining three OS provided features will normally be invoked via the command line or launched as a process. If unsafe inputs are used to construct commands or arguments, it may allow arbitrary OS operations to be performed that can compromise the server.

Micro-Learning Topic: Integer overflow (Detected by phrase)

Matched on "Integer Overflow"

What is this? (2min video)

Integer overflow occurs when the result of arithmetic operation is greater than the maximum value the integer data type can store.
For example, if an integer data type allows integers up to two bytes or 16 bits in length (or an unsigned number up to decimal 65,535), and two integers are to be added together that will exceed the value of 65,535, the result will be integer overflow.
