Certified Ethical Hacker (CEH v11) — Question 9

Shellshock allowed an unauthorized user to gain access to a server. It affected many Internet-facing services, which OS did it not directly affect?

Answer options

• A. Linux
• B. Unix
• C. OS X
• D. Windows

Correct answer: D

Explanation

The correct answer is D, Windows, as Shellshock primarily affected systems running Bash, which is not natively present in Windows environments. In contrast, Linux, Unix, and OS X all utilize Bash and were therefore vulnerable to the exploit.
