What Is Bypass Authentication?

What is Bypassing Authentication? – In computer security, authentication is the process of attempting to verify the digital identity of the sender of a communication. A common example of such a process is the log on process. Testing the authentication schema means understanding how the authentication process works and using that information to circumvent the authentication mechanism. What if we could bypass all authentication mechanisms entirely? We can! This technique is called browser pivoting—essentially, we use our access to the target workstation to inherit permissions from the doctor’s browser and…

What is Privilege Escalation?

What is Privilege Escalation

What is Privilege Escalation? – An attacker can gain access to the network using a non-admin user account and the next step would be to gain administrative privilege escalation. Attacker performs privileges escalation attack which takes advantage of design flaws, programming errors, bugs, and configuration oversights in the OS and software application to gain administrative access to the network and its associated applications. These privileges allows attacker to view critical/sensitive information, delete files, or install malicious programs such as viruses, Trojan, worms, etc. Types of Privilege Escalation Privilege escalation take…

What is Open Redirection?

What is Open Redirection?

This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it, abusing the trust of a given domain to lead users to another. The malicious website serving as the redirect destination could be prepared to look like a legitimate site and try to collect personal…

What is Cross-Site Request Forgery?

What is Cross-Site-Request-Forgery?

What is Cross-Site Request Forgery? – A Cross-Site Request Forgery, or CSRF, attack occurs when a malicious website, email, instant message, application, etc. causes a user’s web browser to perform some action on another website where that user is already authenticated, or logged in. Often this occurs without the user knowing the action has occurred. A successful CSRF exploit can compromise end user data and operation, when it targets a normal user. If the targeted end user is the administrator account, a CSRF attack can compromise the entire web application.…

What is CRLF Injection?

What is CRLF Injection?

What is CRLF? When a browser sends a request to a web server, the web server answers back with a response containing both the HTTP headers and the actual website content. The HTTP headers and the HTML response (the website content) are separated by a specific combination of special characters, namely a carriage return and a line feed. They are also known as CRLF. The server knows when a new header begins and another one ends with CRLF, which can also tell a web application or user that a new…
