CVE-2020-17502
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 · uneditedBarco TransForm N before 3.8 allows Command Injection (issue 2 of 4). The NDN-210 has a web administration panel which is made available over https. There is a command injection issue that will allow authenticated users of the administration panel to perform authenticated remote code execution. An issue exists in split_card_cmd.php in which the http parameters xmodules, ymodules and savelocking are not properly handled. The NDN-210 is part of Barco TransForm N solution and includes the patch from TransForm N version 3.8 onwards.
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.

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 Barco TransForm N installationLocate the Barco TransForm N application in your environment and confirm it is the product in useAffected if Barco TransForm N is present and the version cannot be determined or is below 3.8
-
Check the installed versionAccess the administration interface or system inventory to determine the exact version number of Barco TransForm NAffected if The version is found to be less than 3.8 (for example, 3.7, 3.6, or any version prior to 3.8)
-
Verify NDN-210 web administration panel accessibilityCheck if the NDN-210 web administration panel is accessible on the network or locallyAffected if The web administration panel is exposed and reachable
-
Confirm split_card_cmd.php file presenceLocate the split_card_cmd.php file within the web administration panel directory structureAffected if The split_card_cmd.php file exists in the NDN-210 web administration panel
-
Check authentication status to admin panelDetermine whether valid credentials exist or are configured for access to the web administration panelAffected if Authentication to the admin panel is possible or credentials are configured
You are affected if Barco TransForm N is installed with a version lower than 3.8 and the NDN-210 web administration panel with the vulnerable split_card_cmd.php file is accessible with authentication capability.
