Another day another dollar major security vulnerability.

While this is classed as a critical vulnerability, there's no need to panic as it's difficult to exploit.

A new critical security vulnerability has been discovered in the popular RADIUS network authentication protocol, which is used by networks across the world to help users connect with their services (i.e. everything from broadband ISPs to VPNs, mobile operators and more) and thus could leave them exposed to Man-in-the-Middle (MitM) style attacks.

The vulnerability, which has been dubbed BlastRADIUS by InkBridge Networks (FreeRadius), appears difficult to exploit. But its impact could still be significant if network operators and network administrators who use RADIUS don’t patch their software and devices to protect against the new threat.
