RabbitMQ 4.2.x < 4.2.9 / 4.3.x < 4.3.3 Atom Exhaustion via Shovel Management Endpoint

medium Nessus Plugin ID 362552

Synopsis

The RabbitMQ installed on the remote host is affected by a denial of service vulnerability.

Description

The version of RabbitMQ installed on the remote host is 4.2.x prior to 4.2.9, or 4.3.x prior to 4.3.3. It is, therefore, affected by a denial of service vulnerability:

 - The Shovel parameter parser converts attacker-controlled runtime parameter values (such as the src-protocol, dest-protocol, and AMQP 1.0 dest-properties keys) to Erlang atoms before it bounds them or checks them against a fixed allowlist. A user with the management and policymaker tags can exhaust the node-wide atom table through repeated requests that set Shovel parameters with unique values, and crash the node. (CVE-2026-67415)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to RabbitMQ version 4.2.9, 4.3.3, or later.
