Summary

Zabbix versions from 6.0.0 through 6.0.47, from 7.0.0 through 7.0.28 and from 7.4.0 through 7.4.12 ship a Perl SNMP trap receiver script (zabbix_trap_receiver.pl) that does not neutralize the ZBXTRAP record delimiter in trap content (CWE-143). Someone able to send SNMP traps can inject a record that targets another host, which compromises integrity.

Description from the CNA

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.
