CVE-2021-44522
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been identified in SiPass integrated V2.76 (All versions), SiPass integrated V2.80 (All versions), SiPass integrated V2.85 (All versions), Siveillance Identity V1.5 (All versions), Siveillance Identity V1.6 (All versions < V1.6.284.0). Affected applications insufficiently limit the access to the internal message broker system. This could allow an unauthenticated remote attacker to subscribe to arbitrary message queues.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe vulnerability exists in Siemens SiPass integrated and Siveillance Identity applications where the internal message broker (likely a message queue system like RabbitMQ) does not properly enforce authorization checks. An unauthenticated remote attacker can subscribe to arbitrary message queues, potentially gaining access to sensitive system communications, business logic messages, or credentials transmitted through these queues.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed SiPass Integrated versionLocate the SiPass Integrated installation directory and check the version information file, or use the application's built-in about/version functionality. Common locations include Program Files\Siemens\SiPass or similar installation paths.Affected if The installed version matches 2.76, 2.80, or 2.85 exactly.
-
Identify installed Siveillance Identity versionLocate the Siveillance Identity installation directory and check the version information file, or access the application's version display in the admin interface.Affected if The installed version is 1.5 or falls within the range 1.6 through 1.6.280.0.
-
Locate the internal message brokerIdentify the message queue service (likely RabbitMQ) running on the system. Check for processes listening on typical message broker ports such as 5672 (AMQP) and 15672 (management UI). Review application configuration files for message broker connection strings.Affected if A RabbitMQ or similar message broker is installed and configured for use with the SiPass or Siveillance Identity application.
-
Verify message broker network exposureCheck network bindings and firewall rules to determine if the message broker service is listening on non-localhost interfaces. Use netstat or similar tools to identify listening ports and their bound addresses.Affected if The message broker is bound to 0.0.0.0 or an external-facing network interface, allowing remote connections.
-
Inspect message broker authorization configurationAccess the message broker configuration or management interface. Review the virtual host and queue permission settings to determine if authorization controls properly restrict queue subscription to authorized application components.Affected if Queue permissions allow unauthenticated or unauthorized users to subscribe to arbitrary queues, or default guest user has access from non-localhost addresses.
Your environment is affected if you are running SiPass Integrated version 2.76, 2.80, or 2.85, or Siveillance Identity version 1.5 or between 1.6 and 1.6.280.0, and the internal message broker is accessible from network locations without proper authorization enforcement.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement proper authentication and authorization controls on the message broker to ensure only authenticated and authorized users can subscribe to specific queues. Additionally, network segmentation should restrict access to the internal message broker from untrusted networks.
Siveillance Identity: V1.6.284.0 or later; SiPass Integrated: Contact vendor for patched version
- For Siveillance Identity: Upgrade to version V1.6.284.0 or later to remediate this vulnerability
- For SiPass Integrated: Contact Siemens customer support to obtain the specific patched version for your release (V2.76, V2.80, or V2.85)
