  access to the database. This would allow an attacker to escalate their privileges to a power
  user, compromise the database, or execute commands on the underlying database operating system.

  Because of the functionalities Zabbix offers, an attacker with admin privileges (depending on the
  configuration) can execute arbitrary OS commands on the configured Zabbix hosts and server. This
  results in a severe impact to the monitored infrastructure.

  Although the attacker needs to be authenticated in general, the system could also be at risk if
  the adversary has no user account. Zabbix offers a guest mode which provides a low privileged
  default account for users without password. If this guest mode is enabled, the SQL injection
  vulnerability can be exploited unauthenticated.");
