BlueBorne (security vulnerability)

BlueBorne is a type of security vulnerability with Bluetooth implementations in Android, iOS, Linux and Windows.[1][2][3] It affects many electronic devices such as laptops, smart cars, smartphones and wearable gadgets. One example is CVE-2017-14315. The vulnerabilities were first reported by Armis, the asset intelligence cybersecurity company, on 12 September 2017.[1][2][4][5][6] According to Armis, "The BlueBorne attack vector can potentially affect all devices with Bluetooth capabilities, estimated at over 8.2 billion devices today [2017]."[1]

History

The BlueBorne security vulnerabilities were first reported by Armis, the asset intelligence cybersecurity company, on 12 September 2017.[1]

Technical Information

The BlueBorne vulnerabilities are a set of 8 separate vulnerabilities.[7] They can be broken down into groups based upon platform and type. There were vulnerabilities found in the Bluetooth code of the Android, iOS, Linux and Windows platforms:[8]

  • Linux kernel RCE vulnerability - CVE-2017-1000251[9]
  • Linux Bluetooth stack (BlueZ) information Leak vulnerability - CVE-2017-1000250[10]
  • Android information Leak vulnerability - CVE-2017-0785[11]
  • Android RCE vulnerability #1 - CVE-2017-0781[12]
  • Android RCE vulnerability #2 - CVE-2017-0782[13]
  • The Bluetooth Pineapple in Android - Logical Flaw CVE-2017-0783[14]
  • The Bluetooth Pineapple in Windows - Logical Flaw CVE-2017-8628[15]
  • Apple Low Energy Audio Protocol RCE vulnerability - CVE-2017-14315[16]

The vulnerabilities are a mixture of information leak vulnerabilities, remote code execution vulnerability or logical flaw vulnerabilities. The Apple iOS vulnerability was a remote code execution vulnerability due to the implementation of LEAP (Low Energy Audio Protocol). This vulnerability was only present in older versions of the Apple iOS.[17]

Impact

In 2017, BlueBorne was estimated to potentially affect all of the 8.2 billion Bluetooth devices worldwide,[1] although they clarify that 5.3 billion Bluetooth devices are at risk.[18] Many devices are affected, including laptops, smart cars, smartphones and wearable gadgets.[1][2][4][5][6]

In 2018, after one year after the original disclosure, Armis estimated that over 2 billion devices were still vulnerable.[19][20]

Mitigation

Google provides a BlueBorne vulnerability scanner from Armis for Android.[21] Procedures to help protect devices from the BlueBorne security vulnerabilities were reported by September 2017.[22][23][24]
