CVE-2021-0279Network attack vector

Sensitive-data access and service interruption via hardcoded credentials

Published Jul 15, 2021 · Updated Sep 17, 2024

Hardcoded RabbitMQ credentials in Juniper Networks Contrail Cloud before 13.6.0 allow remote attackers to access administrative services. Deployment configuration enables RabbitMQ by default and assigns static credentials to its administrative interface. Network reachability to that interface is required; successful login exposes unspecified sensitive information and permits service interruption.
