Root security vulnerabilities in alternative router firmware OpenWRT closed

Attackers can exploit quite a few security vulnerabilities in the open-source router firmware and, in the worst case, compromise units as root customers. A fortified model is on the market for obtain.

Critical vulnerabilities

The mission operators advise a swift replace. However, there are at present no indications of ongoing assaults from their aspect.

What else has modified?
