Title
SNMP trap injection in zabbix_trap_receiver.pl
Summary
The Perl SNMP trap receiver script shipped with Zabbix does not properly neutralize the ZBXTRAP record delimiter in trap content. This means someone able to send SNMP traps can inject a record targeting another host, resulting in a loss of integrity.
