What are server-side attacks?

Server-side attacks (also called service-side attacks) are launched directly from an attacker (the client) to a listening service. The “Conficker” worm of 2008+ spread via a number of methods, including a server-side attack on TCP port 445, exploiting a weakness in the RPC service.

What is a server side include attack?

The Server-Side Includes attack allows the exploitation of a web application by injecting scripts in HTML pages or executing arbitrary codes remotely. It can be exploited through manipulation of SSI in use in the application or force its use through user input fields.

What is the meaning of server-side?

Much like with client side, 'server side' means everything that happens on the server, instead of on the client. In the past, nearly all business logic ran on the server side, and this included rendering dynamic webpages, interacting with databases, identity authentication, and push notifications.

What are server-side vulnerabilities?

Server-side request forgery (also known as SSRF) is a web security vulnerability that allows an attacker to induce the server-side application to make requests to an unintended location.

What is server-side forgery attack?

A Server-Side Request Forgery (SSRF) attack involves an attacker abusing server functionality to access or modify resources. The attacker targets an application that supports data imports from URLs or allows them to read data from URLs.

54. Introduction To Server Side Attacks

Is CSRF a client side attack?

CSRF happen at the client side, in technical terms the forgery happens at the client side. The main purpose of CSRF attacks is to force user to take undesirable actions on their online account.

What is difference between CSRF and SSRF?

The target of a CSRF attack is the user. While it is accomplished using flaws in how the web application is designed, its purpose is to perform legitimate but unauthorized actions on the user's account with the web-based service. SSRF forgery, on the other hand, is designed to primarily target the server.

What are the types of attacks?

What is an example of a server-side application?

Server-side code can be written in any number of programming languages — examples of popular server-side web languages include PHP, Python, Ruby, C#, and JavaScript (NodeJS).

What are some of the typical server attacks used by attackers?

What is difference between server-side and client-side?

Client-side means that the processing takes place on the user's computer. It requires browsers to run the scripts on the client machine without involving any processing on the server. Server-side means that the processing takes place on a web server.

What is the difference between backend and server-side?

The back-end, or the "server-side", is basically how the site works, updates and changes. This refers to everything the user can't see in the browser, like databases and servers. Node is your "server-side" in this case. The front-end is everything involved with what the user sees, including design.

Is JavaScript server-side?

JavaScript is the server-side language used to develop services for the Opera Unite feature of the Opera browser. This is a server built into the browser. The JavaScript API includes local file access to a virtual sandboxed file-system and persistent storage via persistent global variables.

What is SSI in web?

Server-side includes (SSI) are a mechanism for employing the web server to perform tasks like displaying files as part of other files or displaying information like the URL of web pages or dates and times dynamically.

What is client-side attack?

Client-side attacks occur when a user downloads malicious content. The flow of data is reversed compared to server-side attacks: client-side attacks initiate from the victim who downloads content from the attacker. Client-side attacks are difficult to mitigate for organizations that allow Internet access.

What is SSI injection?

SSI injection (Server-side Include) is a server-side exploit that lets an attacker send code into an application to be executed later, locally, by the web server. SSI injection attacks can only be successful when the web server permits SSI execution without proper validation.

Is Java client or server-side?

Java: Java is an object-oriented programming language that developers can use for a variety of purposes, including software and application development. Java is one of the most popular server-side programming languages.

Which is faster client-side or server-side?

A server is generally going to be orders of magnitude more powerful than a client machine; and managed code is generally much faster than scripting. However - the client machine also usually has a lot of spare computational power that isn't being used, while the server could be running requests for thousands of users.

What are the four categories of attacks?

Attacks can be classified into four broad categories: snooping, modification, masquerading, and denial of service. In practice, an attack may employ several of these approaches.

What are the two basic types of attacks?

Active & Passive are the two basic types of attacks.

What are the three types of active attacks?

Types of active attacks include: Denial of service (DoS) Distributed Denial of Service (DDoS) Session replay.

Is XSS and CSRF same?

What is the difference between XSS and CSRF? Cross-site scripting (or XSS) allows an attacker to execute arbitrary JavaScript within the browser of a victim user. Cross-site request forgery (or CSRF) allows an attacker to induce a victim user to perform actions that they do not intend to.

Is CSRF a type of XSS?

The key difference between those two attacks is that a CSRF attack requires an authenticated session, while XSS attacks don't. Some other differences are: Since it doesn't require any user interaction, XSS is believed to be more dangerous. CSRF is restricted to the actions victims can perform.

What is DOM based XSS?

Definition. DOM Based XSS (or as it is called in some texts, “type-0 XSS”) is an XSS attack wherein the attack payload is executed as a result of modifying the DOM “environment” in the victim's browser used by the original client side script, so that the client side code runs in an “unexpected” manner.

What is CORS and CSRF?

CSRF is a vulnerability and CORS is a method to relax the same-origin policy. CORS is something you might want to use (in certain circumstances) whereas CSRF is an undesirable design mistake. There are vulnerabilities associated with the CORS mechanism.
