An issue was discovered in the Bose Soundtouch app 18.1.4 for iOS. There is no frontend input validation of the device name. A malicious device name can execute JavaScript on the registered Bose User Account if a speaker has been connected to the app.
The Multicast DNS (mDNS) responder used in BOSE Soundtouch 30 inadvertently responds to IPv4 unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets.
