A critical Microsoft Windows Server bug opens company networks to hackers, allowing them to potentially seize control of IT infrastructures. Microsoft issued a patch for the bug on Tuesday as part of its July Patch Tuesday roundup.
It turns out that the bug is 17 years old. Impacted are Windows Server versions from 2003-2019. The bug, found by researchers at Check Point, received a severity warning of 10 – the highest allowed. Most concerning to researchers however is that the bug is wormable, meaning a single exploit of the flaw can trigger a chain reaction that allows attacks to spread from one computer to another.
