A severe Bluetooth flaw (CVE-2023-45866) allows unauthorized control over Android, Linux, macOS, and iOS devices via keystroke injection without user permission, affecting devices since Android 4.2.2. Discovered by Marc Newlin, no specialized hardware is needed for the exploitation, with full technical details pending release.
Meeting Key Takeaways – Critical Bluetooth Security Flaw (CVE-2023-45866)
– A serious Bluetooth vulnerability, identified as CVE-2023-45866, has been discovered which could allow attackers to take control of various devices including Android, Linux, macOS, and iOS platforms.
– The flaw involves an authentication bypass that lets attackers connect to a device without user confirmation and inject keystrokes for code execution purposes.
– Marc Newlin, the security researcher, reported these vulnerabilities in August 2023.
– The vulnerability exploits an “unauthenticated pairing mechanism” within the Bluetooth specification, fooling the target device into believing it is connecting to a Bluetooth keyboard.
– Attackers can exploit this flaw to run arbitrary commands and install applications by transmitting keystrokes to the vulnerable device if they are physically close enough.
– No special hardware is required for the attack, which can be carried out using a Linux computer with a standard Bluetooth adapter.
– Detailed technical information about the flaw is yet to be released.
– Devices affected include Android versions starting from 4.2.2, iOS, Linux, and macOS systems.
– The vulnerability also affects macOS and iOS devices when Bluetooth is on and a Magic Keyboard has been previously paired, even under Apple’s LockDown Mode.
– Google released an advisory indicating that this vulnerability could lead to remote privilege escalation without the need for additional privileges.
– The vulnerabilities have been widely exposed, which highlights the importance of following updates from credible tech news platforms like The Hacker News via Twitter and LinkedIn.
(Note: As an executive assistant, consider recommending immediate action for addressing this vulnerability within your organization, such as checking for updates from affected vendors, implementing additional security measures, or informing relevant stakeholders about the risk.)
