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 · unedited
Improper neutralization of argument delimiters in a command ('Argument Injection') vulnerability in VR-S1000 firmware Ver. 2.37 and earlier allows an authenticated attacker who can access to the product's command line interface to execute an arbitrary command.
