Kingdom: Time and State
Distributed computation is about time and state. That is, in order for more than one component to communicate, state must be shared, and all that takes time.
Most programmers anthropomorphize their work. They think about one thread of control carrying out the entire program in the same way they would if they had to do the job themselves. Modern computers, however, switch between tasks very quickly, and in multi-core, multi-CPU, or distributed systems, two events may take place at exactly the same time. Defects rush to fill the gap between the programmer's model of how a program executes and what happens in reality. These defects are related to unexpected interactions between threads, processes, time, and information. These interactions happen through shared state: semaphores, variables, the file system, and, basically, anything that can store information.
OAuth2: Insufficient state Parameter Entropy
Abstract
OAuth2 protocol implementations that do not use a
state parameter value with sufficient entropy are susceptible to a CSRF vulnerability.Explanation
OAuth2 protocol implementations that do not use the
In authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a CSRF attack if the
state parameter value with sufficient entropy are susceptible to a CSRF vulnerability that might give an attacker the ability to login to the victim's current application account using a third-party account without any restrictions.In authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a CSRF attack if the
state parameter value is predictable. An attacker can perform a normal OAuth2 process and get the redirection URL that contains the authorization code for the third-party. The attacker can bind their own account to the victim's account for the vulnerable application by enticing a victim to access this URL. If the state parameter is set in the redirection URL but without sufficient entropy, then an attacker can predict the user's state parameter and forge a reliable redirection URL to persuade the victim to access and then implement a CSRF attack.
