Bluetooth Chip Bugs Affect Enterprise Wi-Fi, as Hackers Exploit Cisco 0-Day

In this latest roundup of cyber security news, we look at serious Bluetooth chip-level bugs, a zero-day vulnerability on Cisco software, a raft of Apple security fixes, and a massive customer data breach at Cathay Pacific.

Enterprise Wi-Fi access points vulnerable to Bluetooth bug

A pair of critical Bluetooth bugs could make popular wireless access points used in many enterprises vulnerable to breaches.

The critical vulnerabilities reside in Bluetooth Low Energy (BLE) chips from Texas Instruments which are present in Wi-Fi access points from Cisco, Cisco Meraki and Aruba.

Dubbed Bleedingbit, the bugs were discovered by researchers from Armis and disclosed last week.

If exploited, the vulnerabilities could allow unauthenticated attackers to stealthily break into enterprise networks, take over access points, spread malware, and move laterally across network segments.

The first vulnerability affects TI BLE chips cc2640 and cc2650, used in Cisco and Cisco Meraki Wi-Fi access points. The second bug impacts the Aruba Wi-Fi access point Series 300 with TI BLE chip cc2540 and its use of TI’s over-the-air firmware download (OAD) feature.

“These vulnerabilities are a sharp reminder that we need to ensure the security of the infrastructure we employ to support IoT devices is not undermined by those IoT devices or the protocols that support them,” Brian Honan, CEO at BH Consulting, told Help Net Security.

To exploit either vulnerability, an attacker would have to physically be within Bluetooth range of the targeted access point. TI, Cisco, Cisco Meraki and Aruba have all responded with patches, mitigations and information.
