How can cookies be used as a potential attack vector in web applications?
Cookies can be used as a potential attack vector in web applications due to their ability to store and transmit sensitive information between the client and the server. While cookies are generally used for legitimate purposes, such as session management and user authentication, they can also be exploited by attackers to gain unauthorized access, perform
How can HTML injection be used to steal sensitive information or perform unauthorized actions?
HTML injection, also known as cross-site scripting (XSS), is a web vulnerability that allows an attacker to inject malicious HTML code into a target website. By exploiting this vulnerability, an attacker can steal sensitive information or perform unauthorized actions on the target website. In this answer, we will explore how HTML injection can be used
What is the potential danger of stealing cookies through XSS attacks?
XSS attacks, also known as Cross-Site Scripting attacks, pose a significant threat to the security of web applications. These attacks exploit vulnerabilities in a web application's handling of user input, specifically in the context of injecting malicious scripts into web pages viewed by other users. One potential danger of XSS attacks is the theft of
What is the purpose of the "httpOnly" attribute in HTTP cookies?
