Official description
OS command injection vulnerability exists in CENTUM VP R4.01.00 to R4.03.00, CENTUM VP Small R4.01.00 to R4.03.00, CENTUM VP Basic R4.01.00 to R4.03.00, and B/M9000 VP R6.01.01 to R6.03.02, which may allow an attacker who can access the computer where the affected product is installed to execute an arbitrary OS command by altering a file generated using Graphic Builder.

The underlying weakness: Improper Neutralization of Special Elements used in an OS Command
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command before it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- For any data that will be used to generate a command to be executed, keep as much of that data out of external control as possible. For example, in web applications, this may require storing the data locally in the session's state instead of sending it out to the client in a hidden form field.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
