CVE-2021-44523
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 activity feed database. This could allow an unauthenticated remote attacker to read, modify or delete activity feed entries.
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 confidenceThis vulnerability in SiPass integrated and Siveillance Identity applications allows unauthenticated remote attackers to access the internal activity feed database due to insufficient access controls. An attacker can read, modify, or delete activity feed entries without any authentication, giving them broad access to sensitive operational data.

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 the installed product and versionCheck the installed version of Siemens SiPass integrated or Siveillance Identity on the system. For SiPass integrated, look for versions 2.76, 2.80, or 2.85. For Siveillance Identity, look for version 1.5 or any version between 1.6.0 and 1.6.280.0 inclusive.Affected if The installed version matches one of the affected versions: SiPass Integrated 2.76, 2.80, or 2.85; Siveillance Identity 1.5 or 1.6.x up to 1.6.280.0
-
Verify the application is network accessibleDetermine if the SiPass integrated or Siveillance Identity application is exposed to network access. Check if the application ports or web interface are reachable from untrusted networks.Affected if The application is accessible over the network without authentication requirements
-
Confirm activity feed functionality is presentLocate the activity feed feature or database component within the installed application. This feature stores operational data entries and should be present in affected versions.Affected if The activity feed database component is present and operational on the system
-
Test for unauthenticated access to activity feedAttempt to access the activity feed endpoint or database interface without providing credentials. If the system allows unauthenticated read, modify, or delete operations on activity feed entries, the vulnerability is present.Affected if Unauthenticated access to the activity feed database is possible without any credentials
You are affected if the installed version matches the specified ranges and the application allows unauthenticated network access to the activity feed database.

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.
From vendor dataUpgrade to vendor-supplied patched versions (V1.6.284.0 or later for Siveillance Identity V1.6) and apply any available security patches for SiPass integrated. Implement network segmentation to restrict access to the application from untrusted networks.
