Explanation

According to the CHFI v11 objectives under Web Application Forensics and Analyzing Web- Based Attacks, the primary goal of investigating a command injection attack is to identify and understand the underlying vulnerabilities in the web application's code that allowed the attack to occur. Command injection attacks exploit improper input validation, where user-supplied data is passed directly to system-level commands without adequate sanitization or restriction. From a forensic perspective, investigators analyze web server logs, application logs, and request parameters to determine how malicious input was crafted, which input fields were exploited, and what commands were executed on the server. This analysis helps reconstruct the attack sequence, assess the extent of compromise, and determine whether the attacker achieved privilege escalation, data exfiltration, or lateral movement. Option B correctly reflects this forensic objective, as identifying code-level weaknesses enables organizations to remediate vulnerabilities, apply secure coding practices, and prevent recurrence. Option A focuses on log access control rather than attack analysis. Option C is unrelated to security incidents, and Option D relates more to analytics than forensic investigation.
