CVE Number – CVE-2018-1287

A vulnerability in Apache JMeter could allow an unauthenticated, remote attacker to gain unauthorized access to the JMeterEngine interface on a targeted system.

The vulnerability is due to the binding of the Remote Method Invocation (RMI) Registry to a wildcard host by the affected software when using distributed mode. An attacker could exploit this vulnerability to gain unauthorized access to the JMeterEngine interface on the targeted system, which the attacker could use to send and execute arbitrary code on the system.

Apache has confirmed the vulnerability and released software updates.

Analysis
