CHFI Application, Email and Cloud Forensics Practice Question
This CHFI practice question tests your understanding of application, email and cloud forensics. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An analyst discovers a suspicious file named 'cmd.aspx' in the web root of an IIS server. The file contains ASPX code that executes system commands. The IIS logs show a POST request to '/cmd.aspx' with a 200 status code. Which type of attack is indicated?
A webshell is a malicious script uploaded to a server that allows remote command execution. The file name 'cmd.aspx' and its ability to execute system commands are classic signs.
B
SQL injection
Why wrong: SQL injection targets databases, not file uploads.
C
Cross-site scripting (XSS)
Why wrong: XSS involves injecting client-side scripts; the file is a server-side script.
D
Directory traversal
Why wrong: Directory traversal allows reading arbitrary files, not uploading a webshell.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Real-world example
How this comes up in practice
A practitioner preparing for the CHFI exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
