tag_summary = "Gravity Board X is prone to multiple SQL-injection vulnerabilities
  and a remote command-execution because it fails to sufficiently
  sanitize user-supplied data before using it in an SQL query.

  Exploiting these issues could allow an attacker to execute arbitrary
  code, compromise the application. access or modify data, or exploit
  latent vulnerabilities in the underlying database.

  Gravity Board X 2.0 is vulnerable; other versions may also be
  affected.";
