CompTIA CS0-003 Exam - Topic 2 Question 54 Discussion

Allowing anonymous read access to /etc/passwd is a critical vulnerability because it can expose user account details, aiding attackers in password cracking and privilege escalation.

Option B (Anonymous FTP access) is a risk, but /etc/passwd exposure is more critical as it directly affects user authentication.

Option C (Defender updates disabled) is important, but it does not present an immediate attack vector like credential exposure.

Option D (less escape exploit) is significant, but it requires user interaction, making it less immediate than a global credential leak.

Thus, A is the correct answer, as it represents an immediate, high-impact security risk.
