The attacker does not have to be fully aware of the application's internal workings to leverage these mechanisms. For example, an attacker could view a user's email inbox to discover the user's current state, view the history of the user's last web-page visit to discover the URL of that page, or view the social media profile of the user to gather information about their interests and online behaviour.
Thorough Review Is Critical
Without a thorough review of the application's code, these vulnerabilities can go undetected and hackers might be able to leverage these mechanisms to attack the application.
There are two primary types of defects: logic defects and data-access defects. These two types of defects merit different levels of attention in a software development lifecycle (SDLC). Logic defects are typically harder to detect because they do not affect the user interface or cause any observable changes in behaviour. Data-access defects, on the other hand, directly impact user experience and lead to observable changes in behaviour such as an error message popping up on screen with no indication of what caused it.
So, what should you do? That depends on how much time you have available for code reviews and whether or not you intend to fix those bugs. If your time allows for more extensive reviews and you want to investigate every bug that comes through your door, then doing so is recommended. Otherwise, if time allows for less extensive reviews but you still want to review each bug, then doing so is also recommended. In either case, thoroughness is key!
Blind SQL Injection
The particular vulnerability in this case is a case of blind SQL injection. A form-based web application uses an input to retrieve information from a database and return that information as a result on the web page. In some cases, these forms may be vulnerable to SQL injection due to insufficient input validation. This technique can be used by an attacker to access sensitive data, such as passwords or credit card numbers.
Explanation: Blind SQL injection is when the attacker does not have to be fully aware of the application’s internal workings in order for them to leverage these mechanisms (e.g., view a user's email inbox to discover the current state of their account, view the history of their last web-page visit).
API Over HTTP
An API is essentially a set of functions that can be accessed by multiple applications. In the case of internet-based APIs, this means that you can use these functions remotely without having to interact with the application itself.
The HTTP protocol is used for all API requests and responses. This is because each request sent to an API must be preceded by a request header and the response must include a response header. The HTTP protocol includes several methods, such as GET and POST, which are used to send data or make queries and receive data in response.
An API request has three parts:
1) Header: You need to specify which method you'll use, what type of data will be sent, and which parameters for the function you are requesting.
2) Data: This is the main part of your message.
3) Body: This is where your information begins! Your body should always be formatted using JSON; XML and HTML do not conform to this standard.
Bypassing User Authentication
One of the most dangerous types of vulnerabilities are those that allow an attacker to bypass user authentication. The user is exposed to attacks without any knowledge of their current state, which can be used in a variety of ways by attackers. For example, an attacker could view a user's email inbox to discover the user's current state, view the history of the user's last web-page visit to discover the URL of that page, or view the social media profile of the user to gather information about their interests and online behaviour
In this blog post it is made clear how important digital marketing is for businesses. It also discusses some strategies for effective digital marketing such as using pictures in ads as people respond well to pictures.
The Attacker Can Trick Users Into Clicking Trusted Content
The attacker can display trusted content and use it to trick the victim into clicking on a link, which will then redirect them to a malicious webpage. The attack could be executed by the attacker using JavaScript (for example, an external webpage that is placed within the user's browser), or via social engineering where an attacker sends a URL to the user via email, text message, instant messaging, etc.
