Final answer:
The correct answer is SSRF (Server-side Request Forgery). SSRF manipulates the trusting relationship between web servers.
Step-by-step explanation:
The correct answer is SSRF (Server-side Request Forgery). SSRF manipulates the trusting relationship between web servers. It allows an attacker to send malicious requests from the server, making the server act on behalf of the attacker. This can lead to unauthorized access to data or services that the server can access.
CSRF (Cross-Site Request Forgery) is another web vulnerability, but it does not manipulate the trusting relationship between web servers. It involves tricking an authenticated user into performing unintended actions on a website.
