Описание

Missing Authentication for Critical Function (CWE-306) vulnerability in Apache Artemis, Apache ActiveMQ Artemis. An unauthenticated remote attacker can use the Core protocol to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker. This could potentially result in message injection into any queue and/or message exfiltration from any queue via the rogue broker. This impacts environments that allow both:

  • incoming Core protocol connections from untrusted sources to the broker
  • outgoing Core protocol connections from the broker to untrusted targets This issue affects:
  • Apache Artemis from 2.50.0 through 2.51.0
  • Apache ActiveMQ Artemis from 2.11.0 through 2.44.0. Users are recommended to upgrade to Apache Artemis version 2.52.0, which fixes the issue. The issue can be mitigated by one of the following:
  • Remove Core protocol support from any acceptor receiving connections from untrusted sources. Incoming Core protocol connections are supported by default via the "artemis" acceptor listening on port 61616. See the "protocols" URL parameter configured for the acceptor. An acceptor URL without this parameter supports all protocols by default, including Core.
  • Use two-way SSL (i.e. certificate-based authentication) in order to force every client to present the proper SSL certificate when establishing a connection before any message protocol handshake is attempted. This will prevent unauthenticated exploitation of this vulnerability.
  • Implement and deploy a Core interceptor to deny all Core downstream federation connect packets. Such packets have a type of (int) -16 or (byte) 0xfffffff0. Documentation for interceptors is available at  https://artemis.apache.org/components/artemis/documentation/latest/intercepting-operations.html .

    A flaw was found in Apache Artemis and Apache ActiveMQ Artemis. An unauthenticated remote attacker can exploit a missing authentication for critical function vulnerability by using the Core protocol. This allows the attacker to force a target broker to establish an outbound Core federation connection to an attacker-controlled rogue broker. The primary consequence is the potential for message injection into any queue and/or message exfiltration from any queue via the rogue broker.

Отчет

Red Hat rates this flaw as IMPORTANT severity because it does not enable remote code execution or system compromise (arbitrary code execution), which is Red Hat's threshold for Critical impact. Its impact is limited to message injection and exfiltration via rogue broker federation. Exploitation requires the broker to accept inbound Core protocol connections from untrusted networks with outbound connectivity to attacker-controlled systems. Availability impact is set to None as exploitation does not cause service disruption or broker instability.

Меры по смягчению последствий

To mitigate this issue, restrict Core protocol support on acceptors receiving connections from untrusted sources. The default "artemis" acceptor on port 61616 supports all protocols, including Core. Modify the acceptor URL to explicitly exclude the Core protocol using the "protocols" URL parameter. Alternatively, configure two-way SSL with certificate-based authentication to prevent unauthenticated exploitation. A service restart or reload may be required for changes to take effect.
