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 Siemens SINEMA Remote Connect Server is installedCheck system inventory or installed programs for Siemens SINEMA Remote Connect Server. Look for the product name in Windows Programs and Features, Linux package managers, or application listings.Affected if The product is present on the system
-
Determine the installed version of SINEMA Remote Connect ServerOpen the SINEMA Remote Connect Server management interface and navigate to the About or System Info section to view the version number. Alternatively, check installation logs or the program's file properties for version information.Affected if The installed version is 1.1 or lower (any version <= 1.1)
-
Verify the integrated web server is accessibleAttempt to access the SINEMA Remote Connect Server web interface via its configured URL (typically https://hostname or the IP address on the configured port). Confirm the login page or web portal loads.Affected if The web interface is reachable over the network
-
Confirm the vulnerability is present by testing for reflected parametersUsing a browser or HTTP tool, access a page on the web interface with a test parameter containing a harmless test string (such as ?test=<script>alert(1)</script>). If the JavaScript executes or the parameter value is reflected unsanitized in the response, the vulnerability is present.Affected if User-supplied parameters are reflected in the response without encoding or sanitization
A user is affected if SINEMA Remote Connect Server version 1.1 or lower is installed AND the integrated web server is accessible, allowing reflected parameters to execute unsanitized input.
