What is a Session Guessing attack?

Exploiting weak passwords for user accounts
Guessing session tokens to gain unauthorized access
Intercepting user data in transit
Executing unauthorized scripts in users' sessions

The correct answer is: Guessing session tokens to gain unauthorized access

A Session Guessing attack involves an attacker attempting to gain unauthorized access to a user session by guessing the session tokens associated with that session. Session tokens are unique identifiers generated by a web server to manage user sessions, allowing persistent interaction without requiring repeated authentication. If an attacker can successfully guess a valid session token, they can impersonate the user and access protected resources, bypassing authentication measures. This is particularly dangerous if session tokens are predictable or use insufficient entropy, making them susceptible to brute-force attacks or other heuristic guessing techniques. In contrast, the other options describe different types of attacks or vulnerabilities that do not fit the definition of a Session Guessing attack. Exploiting weak passwords involves gaining access through insecure user credentials, intercepting data pertains to eavesdropping on communications rather than manipulating sessions, and executing unauthorized scripts is related to vulnerabilities like Cross-Site Scripting (XSS), which are distinct from guessing session tokens.
