An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22359 and fix it if it is affected.\n\nWhat it is: CVE-2021-22359 is a high-severity denial of service vulnerability in S5700;S6700, published on 27 May 2021. 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-2021-22359 in the wild and no public exploit code.\n\nAffected product: S5700;S6700. 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-2021-22359/ (Markdown: https://insights.sbomify.com/CVE-2021-22359/index.md)","id":"CVE-2021-22359","markdown":"https://insights.sbomify.com/CVE-2021-22359/index.md","name":"CVE-2021-22359","record":{"aliases":["GHSA-qmm3-r49c-cwh6"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei network switch","requires_auth":"none","summary":"An attacker can cause service disruption on Huawei S5700 and S6700 switches by sending specific messages due to insufficient input validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"s5700_firmware","vendor":"huawei"},{"product":"s6700_firmware","vendor":"huawei"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"There is a denial of service vulnerability in the verisions V200R005C00SPC500 of S5700 and V200R005C00SPC500 of S6700.
