Summary
In summary, you should not redirect users after they have authenticated. An attacker could leverage these vulnerabilities to steal authentication cookies, inject arbitrary HTML content, or perform a cross-site request forgery attack.
What’s an Authentication Cookie?
An authentication cookie is a small bit of data that is sent to the client browser by the server, which allows it to recognize the user and provide them with a less-restrictive experience.
Whenever the user visits a website, they send their username and password in order to gain access. The server would then send an authentication cookie back to the client browser, with information about what site the user was visiting and any other necessary credentials like permissions or settings. This process is known as cross-site request forgery (CSRF).
If attackers were able to intercept this cookie, they could use it on another website without the guest’s knowledge, performing actions such as changing their settings or purchasing items. One way this could be done is by placing malicious code on a website that would steal the authentication cookie set by one website and place it on another site that would then perform actions on behalf of its victim. In addition, if an attacker were able to inject malicious code into an image tag while a victim browsed their favorite retailer’s website, they could perform CSRF attacks.
Vulnerability overview and mitigation strategies
The vulnerabilities exist in the code that checks if the HTTP request is a login request. If it is, then the vulnerable hook will be triggered, which performs some actions as specified by the hook. In this case, the hook will redirect to an arbitrary hostname specified by the attacker.
Vulnerabilities exist in code that checks if the HTTP request is a login request. This can lead to redirection to an arbitrary hostname or injected HTML content. When checking for authentication cookies, there are no proper inputs preventing such attacks from occurring.
