A penetration tester has successfully exploited a buffer overflow vulnerability in a Linux binary. However, the binary has Data Execution Prevention (DEP) enabled and Address Space Layout Randomization (ASLR) disabled. Which exploitation technique is MOST appropriate to achieve code execution in this environment?

A penetration tester has successfully exploited a buffer overflow vulnerability in a Linux binary. However, the binary has Data Execution Prevention (DEP) enabled and Address Space Layout Randomization (ASLR) disabled. Which exploitation technique is MOST appropriate to achieve code execution in this environment?

Answer choices

Why each option matters

Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.

A

Best answer

Return-oriented programming (ROP) to bypass DEP

ROP chains use existing code snippets (gadgets) to perform operations without injecting executable code, bypassing DEP effectively.

B

Distractor review

Simple shellcode injection on the stack

Shellcode injection requires the stack to be executable (no DEP), which is not the case here.

C

Distractor review

ASLR bypass techniques

ASLR is already disabled, so no bypass is needed; this technique does not address DEP.

D

Distractor review

Heap spraying

Heap spraying is typically used to bypass ASLR by filling memory with predictable shellcode, but it does not bypass DEP.

Common exam trap

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Technical deep dive

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.

FAQ

Questions learners often ask

What does this PT0-002 question test?

Read the scenario before looking for a memorised answer.

What is the correct answer to this question?

The correct answer is: Return-oriented programming (ROP) to bypass DEP — DEP (NX bit) prevents execution of code on the stack or heap, so direct shellcode injection will fail. Return-oriented programming (ROP) chains allow the attacker to execute arbitrary code by reusing existing executable code (gadgets) within the program or libraries. Since ASLR is disabled, addresses are predictable, making ROP straightforward.
