{"cve":"CVE-2021-47796","nvd":{"published":"2026-01-16T00:16:23.760","modified":"2026-10-12T14:17:08.200","status":"Deferred","description":"Denver SHO-110 IP cameras expose a secondary HTTP service on TCP port 8001 that provides access to a '/snapshot' endpoint without authentication. While the primary web interface on port 80 enforces authentication, the backdoor service allows any remote attacker to retrieve image snapshots by directly requesting the 'snapshot' endpoint. An attacker can repeatedly collect snapshots and reconstruct the camera stream, compromising the confidentiality of the monitored environment.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":null,"cwes":["CWE-306","CWE-1242"],"references":["http://old.denver.eu/products/smart-home-security/denver-sho-110/c-1024/c-1243/p-3826","https://www.exploit-db.com/exploits/50162","https://www.vulncheck.com/advisories/denver-sho-110-ip-camera-unauthenticated-snapshot-access"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:19:41.481987139+00:00"},"epss":{"cve":"CVE-2021-47796","score":0.00795,"percentile":0.56154,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
