CyberRota Analysis

AI-Generated

The vulnerability affects Jolokia's JSR-160 proxy functionality, where inadequate validation of client-controlled JMX service URLs allows attackers to bypass existing security measures. This flaw can lead to server-side request forgery (SSRF), exposure of JMX credentials, and potential remote code execution if the target JVM is misconfigured. Organizations utilizing Jolokia for JMX monitoring should prioritize patching this vulnerability to mitigate the associated risks.

Original NVD Description

A flaw was found in Jolokia's JSR-160 proxy functionality where insufficient validation of client-controlled JMX service URLs allows a bypass of the denylist introduced to mitigate CVE-2018-1000130. The proxy accepts a `target.url` value from a Jolokia POST request and passes it to `JMXServiceURL` and `JMXConnectorFactory` for establishing the remote JMX connection. The existing denylist only rejects URLs matching `service:jmx:rmi:///jndi/ldap:.*`, which can be bypassed using alternative valid JMX service URL forms, including `ldaps://` schemes or LDAP URLs with a non-empty JMX host component. These URLs are accepted as valid `JMXServiceURL` objects and can cause the Jolokia agent JVM to perform a JNDI lookup against an attacker-controlled LDAP endpoint. This can result in server-side request forgery (SSRF), forwarding of supplied JMX credentials to the remote endpoint, and potentially remote code execution depending on the classes and configuration available in the target JVM.
