SCA: security update for org.apache.artemis:artemis-server (GHSA-fw88-pf9m-p947)

critical Tenable Self-Hosted Container Security Plugin ID 438379

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 .
