CVE-2017-6520

Estado: ModificadaCrítica (9.1)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
