Description
This exploits a command execution in Pi-Hole Web Interface <= 5.5. The Settings > API/Web inetrace page contains the field Top Domains/Top Advertisers which is validated by a regex which does not properly filter system commands, which can then be executed by calling the gravity functionality. However, the regex only allows a-z, 0-9, _.
