Which of the following can be a consequence of insecure output handling?

• A. Data compression issues
• B. Remote Code Execution (RCE)
• C. Performance optimization
• D. Enhanced user interaction

Answer: (B)

Insecure output handling can lead to Remote Code Execution (RCE) because it often involves the improper handling of data that is sent to a client or user interface. If an application does not adequately sanitize or validate the data before outputting it, an attacker could exploit this oversight. For instance, they may inject malicious scripts or commands into the output, which, when executed by the user's browser or system, could allow the attacker to execute arbitrary code on the affected device. This is particularly critical in web applications where user-generated data is reflected in output without proper encoding or escaping.

Remote Code Execution is a severe vulnerability that can result from insecure output handling, as it gives adversaries the ability to execute commands remotely and potentially compromise the system or network. Other consequences of insecure output handling can vary in severity, but they do not pose the same immediate threat of allowing an attacker to gain control over a system.
