CVE-2024-28211Public exploitNetwork attack vector

Unauthenticated code execution via attacker-controlled JMX URL

Published Mar 7, 2024 · Updated Aug 5, 2024

JNDI injection in NAVER Corporation nGrinder before 3.5.9 allows remote attackers to execute arbitrary code through a malicious RMI registry. The unauthenticated /monitor/api/state endpoint passes its ip parameter into MonitorManagerApiController, which builds a partially attacker-controlled JMX URL and gives it to JMXConnectorFactory.connect. A reachable controller can therefore be induced to connect to an attacker-run registry and execute commands with the controller process's privileges.
