Tenda D151 \u0026 D301, published on 21 Jan 2026. 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-2021-47802 exists.\n\nAffected product: Shenzhen Tenda Technology Co.,Ltd. Tenda D151 \u0026 D301. 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-2021-47802/ (Markdown: https://insights.sbomify.com/CVE-2021-47802/index.md)","id":"CVE-2021-47802","markdown":"https://insights.sbomify.com/CVE-2021-47802/index.md","name":"CVE-2021-47802","record":{"aliases":["GHSA-wh72-mc55-37hv"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda router","requires_auth":"none","summary":"Remote attackers can download router configuration files containing admin credentials without authentication via the /goform/getimage endpoint.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"d151_firmware","vendor":"tenda"},{"product":"d301_firmware","vendor":"tenda"}],"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":"Tenda D151 and D301 routers contain an unauthenticated configuration download vulnerability that allows remote attackers to retrieve router configuration files.
