Host Header Injection Vulnerability Scanner Detail

Vulnerability Overview:

Vulnerability: Host Header Injection
Detection Method: Host Header Injection Vulnerability Scanner
Severity: Informational (Further analysis required for risk assessment)
Impact: Host Header Injection can lead to web application security vulnerabilities, allowing attackers to manipulate HTTP headers based on user input. This could result in web cache poisoning, password reset poisoning, and redirection to malicious sites, compromising the security of the application and its users.

Vulnerability Details:

Host Header Injection occurs when a web application accepts user-controlled input that specifies the HTTP Host header without proper validation. This vulnerability allows attackers to construct malicious requests with altered Host headers, potentially leading to harmful actions such as misleading redirects, session fixation, or even exposure to phishing attacks. The scanner tests for this vulnerability by sending a request with a manipulated Host header and checking if the application's response reflects the injected value.

The Importance of Addressing Host Header Injection:

Mitigating Host Header Injection vulnerabilities is crucial for maintaining the integrity and security of web applications. Failure to address these vulnerabilities can expose applications and their users to a range of attacks, undermining trust and potentially leading to data breaches.
