2 In 300 words or more, answer the following: What are some known Kerberos vulnerabilities, and how do they allow a user to escalate privileges? The basic aim of Kerberos is to offer robust authentication for client/server applications, but there are specific weaknesses that malevolent actors can exploit to get elevated capabilities. One of the most noteworthy Kerberos weaknesses is its vulnerability to brute force attacks. Such attacks often include multiple attempts to guess a user account's password by attempting various character combinations. If an attacker is successful, they can use this information to authenticate as the user and obtain access to their resources. Another Kerberos vulnerability is spoofing attacks, in which an attacker assumes the identity of a genuine user by falsifying their credentials. If the attacker is successful, he or she will be able to impersonate the user and obtain access to their resources.

3 Finally, Kerberos is subject to replay attacks, which occur when a hostile actor intercepts and records network traffic that contains authentication messages. The attacker can then replay these communications to obtain access to resources without having to authenticate again. These flaws can be used to gain elevated privileges, get unauthorized access to resources, or impersonate legitimate users. An attacker, for example, who successfully brute forces a user account's password can exploit it to obtain access to sensitive information or to carry out destructive network actions. Similarly, an attacker who successfully spoofs a legitimate user's credentials can access and act on that user's behalf.
