What to do
AI-suggested
2) Disable SMB2 services on the device if configurable or block SMB2 traffic at network firewalls and intrusion prevention systems. 3) Monitor network traffic for unusual SMB2 packets or anomalous behavior indicative of exploitation attempts. 4) Employ network access control (NAC) to restrict which devices can communicate with the Sonos Era 100. 5) Regularly update device firmware and subscribe to Sonos security advisories to apply patches promptly once available. 6) Conduct internal vulnerability assessments and penetration tests focusing on IoT devices and SMB protocol exposure. 7) Educate users and administrators about the risks of exposing IoT devices to untrusted networks. These steps reduce the attack surface and limit the potential for exploitation until a vendor patch is released.
Description
Sonos Era 100 SMB2 Message Handling Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Sonos Era 100 smart speakers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of SMB2 messages. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22384.
