Weekly CISO Digest — Week of 2026-10-19: 16-Year-Old Wi-Fi Vulnerability

Headline Incident: 16-Year-Old Broadcom Wi-Fi Bug Allows Remote Code Execution on Routers Without Password

A critical vulnerability in Broadcom's proprietary 802.11 implementation, present since 2010, allows unauthenticated attackers within Wi-Fi range to execute arbitrary code on affected routers—no password required. Demonstrations revealed attackers could extract Wi-Fi credentials and open reverse shells on devices from Orange Belgium and Proximus, with over 1.5 million routers exposed in Belgium alone. The flaw impacts major ISPs including Orange Belgium, Proximus, VOO, and Telenet, and likely affects millions globally. Attackers can compromise home and enterprise networks silently, bypassing traditional access controls. Immediate patching and network segmentation are essential to mitigate this threat, especially for organizations relying on consumer-grade or legacy Wi-Fi hardware.
