CyberRota Analysis
AI-GeneratedRabbitMQ's management plugin is vulnerable to a cross-origin resource sharing (CORS) misconfiguration that allows reflected origins and credentials to be sent in responses when the wildcard CORS setting is enabled. This flaw can be exploited by a malicious web page to leverage an administrator's cached HTTP Basic credentials, enabling unauthorized access to the management API for state-changing actions. Organizations using affected versions should prioritize patching to versions 3.13.17, 4.0.22, 4.1.13, or 4.2.6 to mitigate this high-severity risk.

Original NVD Description
RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.17, 4.0.22, 4.1.13, and 4.2.6, match_origin/1 returned the bare reflected Origin and allowed credentials even when the wildcard "" was configured, so the response echoed the attacker's origin together with Access-Control-Allow-Credentials. The affected code is rabbit_mgmt_cors.erl. When the management plugin is configured with a wildcard CORS origin (cors_allow_origins = ""), the handler reflects the request Origin back in Access-Control-Allow-Origin and also sends Access-Control-Allow-Credentials: true. A malicious web page that a signed-in administrator visits can then use that administrator's cached HTTP Basic credentials to issue authenticated, state-changing requests to the management API. Preconditions include The management plugin is configured with the wildcard cors_allow_origins = "*", which is an explicit operator misconfiguration A target administrator has a cached HTTP Basic-auth session in the browser. This issue is fixed in versions 3.13.17, 4.0.22, 4.1.13, and 4.2.6.
