The correct answer is D. Directory traversal was performed to obtain a sensitive file for further reconnaissance. The log entry shows URL-encoded sequences (%2E%2E) representing “..”, which is characteristic of a directory traversal attempt. This technique is used to access files such as /etc/passwd for reconnaissance. Even if unsuccessful, the pattern clearly indicates a traversal

  • BA PHP injection was leveraged to ensure that the sensitive file could be accessed.
  • CBase64 was used to prevent the IPS from detecting the fully encoded string.
