Attackers can send a continuous loop of unauthenticated commands to override the physical remote, change volume and mute, and reset all picture and audio calibration settings.","cvssScore":4.6,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L","cwes":["CWE-306"],"vendors":[],"products":[],"references":[{"url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research","tags":[]},{"url":"https://www.vulncheck.com/advisories/hisense-vidaa-smart-tv-upnp-dlna-missing-authentication","tags":[]}],"exploitRefs":[{"url":"https://github.com/yehia-mamdouh/Hisense-Smart-TV-Security-Research","tags":[]}],"hasPoc":true,"ai":null}
