CompTIA Security+ SY0-701 Practice Question

A banking application verifies a user's account balance before processing a withdrawal. However, due to a delay between the balance check and the withdrawal transaction, an attacker manages to initiate multiple withdrawals before the balance is updated, resulting in an overdraft. What type of vulnerability does this scenario illustrate?

  • SQL injection flaw due to improper query handling.

  • Brute force attack targeting user authentication mechanisms.

  • Race condition allowing exploitation of timing gaps between operations.

  • Cross-site scripting (XSS) vulnerability in the input fields.
