Description

Sonos Era 300 SMB Response Out-Of-Bounds Access Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Sonos Era 300. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the DataOffset field within SMB responses.
