Cross-Origin Request Blocking (CORB) Bypass
Cross-Origin Request Blocking (CORB) Bypass is a problem in web security where a hacker can bypass the same-origin policy in a web application by using malicious code to access data from a different origin. This can result in the theft of sensitive information, such as login credentials or financial information.
To understand the problem, you need to understand the same-origin policy. This is a security mechanism built into web browsers that prevents malicious code from accessing data from a different origin. An origin is simply the combination of a domain name and a protocol (http or https).
However, sometimes web applications use cross-origin requests to load data from different domains. This is where CORB comes in. CORB is designed to block any cross-origin requests that could be used to steal sensitive information.
Unfortunately, hackers have found ways to bypass CORB. They do this by using various techniques, such as injecting specially-crafted JavaScript code or exploiting known vulnerabilities in web applications.
To protect yourself from CORB bypass attacks, it’s important to keep your web applications up to date with the latest security patches and to use best practices for secure coding. Additionally, you may want to use tools like content security policies (CSP) and web application firewalls (WAF) to help protect against these types of attacks.
