Alvarez Bravo said, two months ago, I passed the DELL security website to inform them of this matter, but they did not make any response, did not indicate that they have been informed of this matter. Unfortunately, I don’t have those affected KVM switches list list. All I know is that they have the same firmware. The original manufacturer of these firmware is the United States Emerson Electric’s Avocent, Avocent is the world’s leading supplier of KVM switching and connectivity solutions."
, a researcher from Labs Kabasiji (Kaspersky), also encountered similar problems, he said he had also contacted the company on the matter DELL. But as of press time before the author, DELL still declined to comment.
