CVE-2021-45106
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 SICAM TOOLBOX II (All versions). Affected applications use a circumventable access control within a database service. This could allow an attacker to access the database.
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 · moderate confidenceSICAM TOOLBOX II contains a database service with a circumventable access control mechanism. An attacker could potentially bypass the access controls and gain unauthorized access to the database, potentially allowing data exposure or manipulation.

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 if SICAM TOOLBOX II is installedCheck the installed programs or application list on the system for Siemens SICAM TOOLBOX II. On Windows, use the Add/Remove Programs list or check the installation directory where Siemens software is typically installed.Affected if SICAM TOOLBOX II is present on the system
-
Locate the database service componentIdentify the database service that ships with SICAM TOOLBOX II. Look for database executables, services, or processes related to the application in the installation directory or running services.Affected if A database service component bundled with SICAM TOOLBOX II is found running on the system
-
Verify database service accessibilityTest if the database service can be accessed without authentication. Attempt to connect to the database port or interface used by SICAM TOOLBOX II without providing credentials.Affected if The database service accepts connections without requiring proper authentication credentials
-
Check network exposure of the database serviceReview network listeners and firewall rules to determine if the database service port is bound to network interfaces accessible from non-localhost sources.Affected if The database service is listening on a network interface other than localhost and is accessible remotely
-
Inspect access control configurationExamine the database service configuration files or settings for any authentication enforcement mechanisms, role-based access controls, or password protection settings.Affected if Access control mechanisms are absent, disabled, or improperly configured in the database service
If SICAM TOOLBOX II is installed and its database service can be accessed without proper authentication or authorization, the environment is affected by this vulnerability.

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 dataImplement proper authentication and authorization checks within the database service layer. Restrict database access to authorized users and applications only, and validate all access requests server-side.
