{"apiVersion":"1.0","identifier":"CVE-2026-76070","description":"Netis NC63 firmware through V3.0.0.3327 contains a stack-based buffer overflow vulnerability that allows unauthenticated remote attackers to overwrite saved stack state by submitting an oversized Base64-encoded password to the login handler in /bin/netis.cgi. Attackers can exploit the custom Base64 decoder-s lack of output length validation against the fixed-size stack buffer to achieve remote code execution with root privileges, as the Boa web server executes the CGI environment as root.","publishedAt":"2026-08-24T16:17:22","lastModifiedAt":"2026-08-24T19:16:58","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-76070","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.01003,"riskScore":1.07,"affectedProduct":"Netis NC63","affectedVersions":"<=V3.0.0.3327","vulnerabilityType":"Firmware","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-76070","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-76070","en":"https://www.redsauce.net/en/cves/CVE-2026-76070","fr":"https://www.redsauce.net/fr/cves/CVE-2026-76070","pt":"https://www.redsauce.net/pt/cves/CVE-2026-76070","de":"https://www.redsauce.net/de/cves/CVE-2026-76070","sk":"https://www.redsauce.net/sk/cves/CVE-2026-76070","el":"https://www.redsauce.net/el/cves/CVE-2026-76070"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-76070"}}
