At a glance: RabbitMQ contains multiple critical vulnerabilities for arbitrary code execution and authentication bypass that require immediate patching.
Multiple vulnerabilities have been discovered in RabbitMQ that enable remote code execution, privilege escalation and data manipulation. The BSI classifies the vulnerabilities as critical and recommends immediate patching.
The message queue software RabbitMQ contains multiple vulnerabilities that enable various attack scenarios: attackers can execute arbitrary code, obtain elevated privileges, bypass security measures and cause denial-of-service conditions. Additionally, cross-site scripting attacks, data manipulation and disclosure of confidential information are possible.
For CISOs, this represents a high risk, particularly in infrastructures that use RabbitMQ for messaging and workflow orchestration. Affected systems could become a launchpad for lateral movement in the network through compromised message brokers. The combination of code execution and authentication bypass potentially enables attackers to establish persistent access.
The BSI recommends checking the RabbitMQ versions in use and performing patches. Isolating systems that cannot be patched or implementing network segmentation of RabbitMQ components reduces exposure risk until stable security updates are available. Additionally, message broker logs should be monitored for suspicious patterns.
