Source: CVE Database V5
Vendor/Project: rabbitmq
Product: rabbitmq-server

Description

RabbitMQ is a messaging and streaming broker. Prior to versions 4.1.13, 4.2.7, and 4.3.0, is_authorized/2 uses is_authorized_monitor for all methods. DELETE resets rabbit_core_metrics:reset_auth_attempt_metrics(). Impact is cosmetic (counters only, no log erasure), but inconsistent with rabbit_mgmt_wm_reset.erl which requires admin for the analogous operation. A monitoring-tagged user can reset the per-node authentication-attempt counters via DELETE /api/auth/attempts/:node, erasing evidence of brute-force activity. The sibling endpoint wm_reset requires administrator. Preconditions include Management plugin enabled monitoring tag. This issue is fixed in versions 4.1.13, 4.2.7, and 4.3.0.

Technical Analysis

RabbitMQ versions before 4.1.13, 4.2.7, and 4.3.0 have a missing authorization check (CWE-862) in the management plugin's DELETE /api/auth/attempts/:node endpoint. A user with monitoring privileges can reset authentication attempt counters, which erases evidence of brute-force attempts. This is inconsistent with the sibling wm_reset endpoint that requires admin rights. The vulnerability is fixed in the specified versions.

Potential Impact

The vulnerability allows a monitoring-tagged user to reset authentication attempt counters, erasing evidence of brute-force activity on a node. This impact is cosmetic and does not affect logs or system integrity. There is no indication of privilege escalation or direct compromise from this issue.

Mitigation Recommendations

Upgrade rabbitmq-server to version 4.1.13, 4.2.7, or 4.3.0 or later where this authorization issue is fixed. No additional mitigation is required as the fix is official and addresses the missing authorization.
