CVE-2023-22601 involves the use of insufficiently random values. Imagine a lottery where the winning numbers are predictable – it quickly loses its fairness.

Taken alone, each vulnerability presents a considerable risk, but when combined or “chained,” they pave a veritable highway for exploitation. The cyber attacker managed to exploit these vulnerabilities in sequence, allowing them to gain control over any connected router or even target a specific router using its serial number. It’s a sobering reminder that in the world of cybersecurity, the whole is often much worse than the sum of its parts.
