Smart Home Ruvie CCTV Bridge DVR Service, published on 9 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-47710 in the wild and no public exploit code.\n\nAffected product: COMMAX Co., Ltd. Smart Home Ruvie CCTV Bridge DVR Service. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-47710/ (Markdown: https://insights.sbomify.com/CVE-2021-47710/index.md)","id":"CVE-2021-47710","markdown":"https://insights.sbomify.com/CVE-2021-47710/index.md","name":"CVE-2021-47710","record":{"aliases":["GHSA-cx3r-78v3-hh67"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Smart Home DVR","requires_auth":"none","summary":"Unauthenticated attackers can retrieve plain-text RTSP credentials and DVR settings from the COMMAX Smart Home Ruvie CCTV Bridge via a specific endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"COMMAX Smart Home System is a smart IoT home solution that allows an unauthenticated attacker to disclose RTSP credentials in plain-text by exploiting the /overview.asp endpoint.
