Attackers can send a crafted unauthenticated RTSP request to cause a buffer overflow and application crash. The device will not be able to perform its main purpose of video encoding and streaming for up to a minute, until it automatically reboots. Attackers can send malicious requests once a minute, effectively disabling the device.","published":"2020-10-06T13:15:14.000Z","lastModified":"2026-06-17T03:05:18.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["szuray/iptv\\/h.264 video encoder firmware","szuray/iptv\\/h.265 video encoder firmware","jtechdigital/h.264 iptv encoder 1080p\\@60hz firmware","provideoinstruments/vecaster-hd-h264 firmware","provideoinstruments/vecaster-hd-hevc firmware","provideoinstruments/vecaster-4k-hevc firmware","provideoinstruments/vecaster-hd-sdi firmware"],"epss":{"score":0.35393,"percentile":0.98451,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2020-10-19","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":48903,"kind":"exploit","title":"HiSilicon Video Encoders - Unauthenticated RTSP buffer overflow (DoS)","url":"https://www.exploit-db.com/exploits/48903","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/hardware/webapps/48903.sh","file":"exploits/hardware/webapps/48903.sh","published":"2020-10-19","added":"2020-10-19","updated":"2020-10-19","author":"Alexei Kojenov","type":"webapps","platform":"hardware","port":null,"verified":false,"codes":["CVE-2020-24214"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 35.4%, higher than 98% of all known CVEs.
