What is a CVE in web application?
The Common Vulnerabilities and Exposures (CVE) list includes all known security vulnerabilities. Since malicious actors are aware of the list, they regularly look for components without the appropriate security patch updates. Once they can compromise one component of the web application, they can gain access to the application’s data, too.
Why do web applications use URL restrictions?
Applications use URL restrictions to prevent non-privileged users from accessing privileged data and resources. Every clickable button in a web application directs to a URL. A failure to restrict access vulnerability means that while clicking the button in the application would prevent access, directly using the URL into the browser allows access. When an application fails to restrict URL access, malicious actors can use “forced browsing” for an attack.
How does a CSRF attack work?
A CSRF attack leverages social engineering methods to get a user to change information, like user name or password, in an application . Unlike malware or cross-site scripting (XXS) attacks, a CSRF requires a user to be logged into the application that uses only session cookies for tracking sessions or validating user requests. Once the user takes the intended action, the attacker leverages the browser to perform the rest of the attack, such as transferring funds, without the user realizing what happened. For example, as OWASP explained, the “buy now” feature on retail websites is easy to exploit through a CSRF attack because the attacker can use the cookies stored on the browser that saves the payment data to complete the attack.
Why is debugger important?
