QVR Elite, published on 14 Jan 2022. 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-2021-38682 in the wild and no public exploit code.\n\nAffected product: QNAP Systems Inc. QVR Elite. 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-2021-38682/ (Markdown: https://insights.sbomify.com/CVE-2021-38682/index.md)","id":"CVE-2021-38682","markdown":"https://insights.sbomify.com/CVE-2021-38682/index.md","name":"CVE-2021-38682","record":{"aliases":["GHSA-vr5c-78wc-f9c4"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP surveillance software","requires_auth":"none","summary":"Attackers can execute arbitrary code on QNAP devices via a stack buffer overflow in QVR surveillance applications.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qnap","cpe":[{"product":"qvr_elite","vendor":"qnap"},{"product":"qvr_guard","vendor":"qnap"},{"product":"qvr_pro","vendor":"qnap"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A stack buffer overflow vulnerability has been reported to affect QNAP device running QVR Elite, QVR Pro, QVR Guard.
