Description: Host header injection is a type of cyber attack where an attacker manipulates the Host header in HTTP requests to redirect traffic to an unauthorized or malicious server. This header is crucial in the HTTP protocol as it indicates to the server the domain name being accessed. By modifying this header, the attacker can trick the server into believing that the request comes from a legitimate source, potentially leading to the exposure of sensitive data or the execution of unauthorized actions. This type of attack can be used to bypass security measures such as firewalls and intrusion detection systems, making it a dangerous technique in an attacker’s arsenal. Host header injection can also be utilized in various contexts of web applications and services, facilitating actions such as content spoofing or phishing attacks. Understanding this type of attack is essential for implementing effective security measures and protecting organizational network infrastructure.
