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: 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: Path traversal (Detected by phrase)

Matched on "Path Traversal"

What is this? (2min video)

Path traversal vulnerabilities occur when inputs that have not been sufficiently validated or sanitised are used to build directory or file paths. If an attacker can influence the path being accessed by the server, they may be able to gain unauthorised access to files or even execute arbitrary code on the server (when coupled with file upload functionality).
