CVE-2024-23321 | Apache RocketMQ: Unauthorized Exposure of Sensitive Data

For RocketMQ versions 5.2.0 and below, under certain conditions, there is a risk of exposure of sensitive Information to an unauthorized actor even if RocketMQ is enabled with authentication and authorization functions. An attacker, possessing regular user privileges or listed in the IP whitelist, could potentially acquire the administrator's account and password through specific interfaces. Such an action would grant them full control over RocketMQ, provided they have access to the broker IP address list. To mitigate these security threats, it is strongly advised that users upgrade to version 5.3.0 or newer. Additionally, we recommend users to use RocketMQ ACL 2.0 instead of the original RocketMQ ACL when upgrading to version Apache RocketMQ 5.3.0.

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:L)
A normal user session is enough; they don’t have to be admin.
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.
