Which of the following threat types can occur when an application does not properly validate input and can be leveraged to send users to malicious sites that appear to be legitimate?
Unvalidated redirects and forwards occur when an application does not properly validate input that controls the destination of a redirect or forward. This allows attackers to craft malicious URLs that redirect users to unwanted or malicious sites, making them appear legitimate. This type of threat can lead users to phishing sites or sites hosting malware, leveraging the trust users have in the application to validate their navigation.
A. Unvalidated redirects and forwards
When an application doesn't validate input properly, it may inadvertently allow attackers to craft URLs that redirect users to malicious sites. This is known as unvalidated redirects and forwards, and it poses a significant risk because users might be tricked into believing they're navigating within a legitimate environment.
Unvalidated redirects and forwards occur when an application does not properly validate user input before redirecting or forwarding requests. Attackers exploit this weakness to redirect users to malicious sites that appear legitimate, leading to phishing attacks, malware downloads, or credential theft.
