A security engineer receives reports through the organization’s bug bounty program about remote code execution in a specific component in a custom application. Management wants to properly secure the component and proactively avoid similar issues. Which of the following is the best approach to uncover additional vulnerable paths in the application?

  • A. Implement fuzz testing focused on the component and inputs uncovered by the bug bounty program.
  • B. Leverage a software composition analysis tool to find all known vulnerabilities in dependencies.
  • C. Use a vulnerability scanner to perform multiple types of network scans to look for vulnerabilities.
  • D. Utilize a network traffic analyzer to find malicious packet combinations that lead to remote code execution.
  • E. Run an exploit framework with all payloads against the application to see if it is able to gain access.

Selected Answer: A
Implementing fuzz testing focused on the specific component and inputs identified by the bug bounty program is the best approach to uncover additional vulnerable paths in the application. - By concentrating on the component where the remote code execution (RCE) vulnerability was found, fuzz testing can efficiently identify similar weaknesses in the code. - Fuzz testing generates a wide range of unexpected or random inputs, helping to discover edge cases that may not be covered by standard testing. - It helps identify complex and subtle bugs that could lead to security issues like buffer overflows, injection flaws, or logic errors leading to RCE. - Fuzzing tools automate the process of input generation and testing, allowing for extensive coverage without excessive manual effort. - Integrating fuzz testing into the development process helps catch vulnerabilities early, reducing the cost and effort required to fix them.
