Smart Home IoT Control System, published on 9 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-47708 exists.\n\nAffected product: COMMAX Co., Ltd. Smart Home IoT Control System. 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-2021-47708/ (Markdown: https://insights.sbomify.com/CVE-2021-47708/index.md)","id":"CVE-2021-47708","markdown":"https://insights.sbomify.com/CVE-2021-47708/index.md","name":"CVE-2021-47708","record":{"aliases":["GHSA-5j3x-hf29-3qgv"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["security_bypass","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Smart Home IoT Control System","requires_auth":"none","summary":"Attackers can bypass authentication and gain unauthorized access to COMMAX Smart Home IoT Control Systems via SQL injection in the login parameter.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"COMMAX Smart Home System CDP-1020n contains an SQL injection vulnerability that allows attackers to bypass authentication by injecting arbitrary SQL code through the 'id' parameter in 'loginstart.asp'.
