A remote unauthenticated attacker can send a crafted UDP packet to execute arbitrary commands as root. The service-s authentication uses a hardcoded salt and an all-zero wildcard MAC bypass, rendering it ineffective.","publishedAt":"2026-08-27T13:18:34","lastModifiedAt":"2026-08-27T17:19:52","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74233","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.02633,"riskScore":1.21,"affectedProduct":"Zbtlink Firmware","affectedVersions":"unknown","vulnerabilityType":"Firmware","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74233","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74233","en":"https://www.redsauce.net/en/cves/CVE-2026-74233","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74233","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74233","de":"https://www.redsauce.net/de/cves/CVE-2026-74233","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74233","el":"https://www.redsauce.net/el/cves/CVE-2026-74233"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74233"}}
