Zabbix Perl SNMP Trap Receiver Script Record Delimiter Injection
CVE-2026-59787 Published on October 5, 2026
SNMP trap injection in zabbix_trap_receiver.pl
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.
Vulnerability Analysis
CVE-2026-59787 can be exploited with network access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity and availability.
Weakness Type
Improper Neutralization of Record Delimiters
The software receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as record delimiters when they are sent to a downstream component. As data is parsed, an injected/absent/malformed delimiter may cause the process to take unexpected actions.
