Micro-Learning Topic: Regular expression denial of service (Detected by phrase)

Matched on "Regular Expression Denial of Service"

What is this? (2min video)

Denial of Service (DoS) attacks caused by Regular Expression which causes the system to hang or cause them to work very slowly when attacker sends a well-crafted input(exponentially related to input size).Denial of service attacks significantly degrade the service quality experienced by legitimate users. These attacks introduce large response delays, excessive losses, and service interruptions, resulting in direct impact on availability.

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.

Micro-Learning Topic: Denial of service (Detected by phrase)

Matched on "Denial of Service"

The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others.

Micro-Learning Topic: Prototype pollution (Detected by phrase)

Matched on "Prototype Pollution"

What is this? (2min video)

By adding or modifying attributes of an object prototype, it is possible to create attributes that exist on every object, or replace critical attributes with malicious ones. This can be problematic if the software depends on existence or non-existence of certain attributes, or uses pre-defined attributes of object prototype (such as hasOwnProperty, toString or valueOf).

Micro-Learning Topic: Server-side request forgery (Detected by phrase)

Matched on "Server-side Request Forgery"

What is this? (2min video)

Server-Side Request Forgery (SSRF) vulnerabilities are caused when an attacker can supply or modify a URL that reads or sends data to the server. The attacker can create a malicious request with a manipulated URL, when this request reaches the server, the server-side code executes the exploit URL causing the attacker to be able to read data from services that shouldn't be exposed.
