CVE-2026-112330 GDATASoftwareAG CVE debrief

Who should care

Defenders responsible for RabbitMQ and Motor.NET deployments should assess exposure and apply patches to prevent potential denial of service attacks. Additionally, security teams and vulnerability management teams should be aware of the potential risks and take steps to verify exposure and apply patches. Operators and administrators of Motor.NET and RabbitMQ should also be aware of the vulnerability and take steps to mitigate potential risks. This includes

Why it matters

Defenders should prioritize verifying exposure and applying patches, as the vulnerability allows for a permanent denial of service.

• Potential permanent denial of service
• Verification of Motor.NET version and exposure to RabbitMQ
• Patching to upgrade to Motor.NET version 0.19.0 or later
• Monitoring RabbitMQ queues for suspicious activity

Technical summary

The vulnerability exists in Motor.NET before version 0.19.0 and allows an attacker to cause a permanent denial of service by sending a message with crafted CloudEvents headers to a consumed RabbitMQ queue. The application fails to properly handle certain CloudEvents headers, leading to an unhandled exception that crashes the service. The unacknowledged message is redelivered on restart, causing a permanent crash-loop. This issue highlights the importance of proper input validation and error handling in cloud-based applications.

Defensive priority

Defenders should prioritize verifying exposure and applying patches, as the vulnerability allows for a permanent denial of service.

Recommended defensive actions

• Verify Motor.NET version and exposure to RabbitMQ
• Apply patch to upgrade to Motor.NET version 0.19.0 or later
• Monitor RabbitMQ queues for suspicious activity
• Implement compensating controls to limit access to RabbitMQ queues
• Review and update incident response plans to address potential denial of service attacks
• Conduct regular security audits to identify and address vulnerabilities in Motor.NET and RabbitMQ deployments
• Establish a process for tracking and addressing exceptions and retesting remediated assets

Evidence notes
