CISSP Software Development Security Practice Question

This CISSP practice question tests your understanding of software development security. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

During a security assessment, a penetration tester discovers that a web application exposes internal IP addresses in error messages. Which vulnerability category does this represent?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Security misconfiguration

Exposing internal IP addresses in error messages is a classic example of a security misconfiguration (C). The web application is likely configured to output detailed error messages (e.g., stack traces or debug information) that include internal network details, which should be suppressed in production environments. This violates the principle of least information disclosure and is categorized under security misconfiguration because it stems from improper default or runtime settings.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Broken access control

    Why it's wrong here

    Broken access control involves unauthorized access to functionality or data, not error messages.

  • Sensitive data exposure

    Why it's wrong here

    While IP addresses could be considered sensitive, the root cause is misconfiguration allowing detailed error messages.

  • Security misconfiguration

    Why this is correct

    Verbose error messages are a configuration issue that should be disabled in production.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Insecure deserialization

    Why it's wrong here

    Insecure deserialization involves untrusted data being used to abuse an application's logic, not error message details.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse the disclosure of internal IP addresses with 'sensitive data exposure' (B), but CISSP categorizes this under security misconfiguration because the root cause is a failure to properly configure error handling, not the inherent sensitivity of the data itself.

Detailed technical explanation

How to think about this question

Under the hood, this vulnerability often arises from web frameworks (e.g., ASP.NET, Spring Boot) that enable detailed error pages or stack traces when a custom error handler is not configured. For example, an ASP.NET application with <customErrors mode="Off"> in web.config will expose internal server paths and IP addresses in yellow screens of death. In real-world scenarios, an attacker can use this information to map internal network ranges (e.g., 10.0.0.0/8) and plan further attacks like lateral movement or SSRF exploitation.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
