CVE-2022-43400
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 Siveillance Video Mobile Server V2022 R2 (All versions < V22.2a (80)). The mobile server component of affected applications improperly handles the log in for Active Directory accounts that are part of Administrators group. This could allow an unauthenticated remote attacker to access the application without a valid account.
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 Siveillance Video Mobile Server component fails to properly validate authentication for Active Directory accounts that are members of the Administrators group. This improper handling allows an unauthenticated remote attacker to bypass authentication and gain access to the mobile server application without providing valid credentials.

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.
-
Confirm Siveillance Video Mobile Server is installedLocate the Siveillance Video Mobile Server installation on the system or check for the running service using system inventory tools or service management consolesAffected if The product is present on the system
-
Determine installed versionCheck the installed version of Siveillance Video Mobile Server against the affected range (versions prior to 22.2a or build 80) using version information from the application, installation directory, or system registryAffected if The installed version is lower than 22.2a(80)
-
Verify Active Directory authentication is enabledInspect the mobile server configuration settings to determine if Active Directory/LDAP authentication integration is configured and activeAffected if Active Directory authentication is configured and in use
-
Check for Administrator group members in AD configurationReview the mobile server's Active Directory integration settings to identify if any AD accounts or groups assigned to administrative roles are members of the Domain Admins or local Administrators groupAffected if AD accounts that are members of the Administrators group are configured for mobile server access
A user is affected if Siveillance Video Mobile Server version is below 22.2a(80) AND Active Directory authentication is enabled with Administrator group members configured for access.

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 · scoped22.2a
Upgrade Siveillance Video Mobile Server to version V22.2a (80) or later to resolve the authentication bypass vulnerability. Until the patch is applied, consider network segmentation and restricting access to the mobile server component from untrusted networks.
V22.2a (80) or later
- 1. Identify the current version of Siveillance Video Mobile Server installed in your environment
- 2. Download Siveillance Video Mobile Server V22.2a (80) or later from the Siemens cert-portal or official support channels
- 3. Review the Siemens upgrade documentation before proceeding
- 4. Perform a backup of the current configuration and database
- 5. Stop the Siveillance Video Mobile Server service
- 6. Install the upgrade to version V22.2a (80) or later
- 7. Verify the upgrade was successful by checking the version number
- 8. Restart the Siveillance Video Mobile Server service
