An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21736 in the wild and no public exploit code.\n\nAffected product: ZXHN HS562. 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-2021-21736/ (Markdown: https://insights.sbomify.com/CVE-2021-21736/index.md)","id":"CVE-2021-21736","markdown":"https://insights.sbomify.com/CVE-2021-21736/index.md","name":"CVE-2021-21736","record":{"aliases":["GHSA-j56v-m9w9-5r65"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ZTE smart camera","requires_auth":"high_privilege","summary":"Users with revoked sharing permissions can still control the camera, allowing unauthorized actions like restarting or resetting the device.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zte","cpe":[{"product":"zxhn_hs562_firmware","vendor":"zte"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-276","name":"Incorrect Default Permissions"}],"description":"A smart camera product of ZTE is impacted by a permission and access control vulnerability.
