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: Buffer overflow (Detected by phrase)

Matched on "Buffer Overflow"

What is this? (2min video)

A buffer overflow condition exists when a program attempts to put more data in a buffer than it can hold or when a program attempts to put data in a memory area past a buffer.

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.

Micro-Learning Topic: Information disclosure (Detected by phrase)

Matched on "Information Exposure"

Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser.

Micro-Learning Topic: Use-after-free (Detected by phrase)

Matched on "Use After Free"

What is this? (2min video)

Dereferencing pointers to objects that have already been freed opens the door to execution of arbitrary code. Attackers may be able to insert instructions at the freed memory location in order to trigger the exploit when the pointer is used after the memory has been freed.

Micro-Learning Topic: Weak input validation (Detected by phrase)

Matched on "Improper Input Validation"

Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent to an interpreter as part of a command or query. The attacker’s hostile data can trick the interpreter into executing unintended commands or accessing data without proper authorization.
