An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2016-8786 and fix it if it is affected.\n\nWhat it is: CVE-2016-8786 is a high-severity denial of service vulnerability in Huawei Technologies Co., Ltd. S12700, S5700, S6700, S7700, S9700, published on 9 Mar 2018. 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-2016-8786 in the wild and no public exploit code.\n\nAffected product: Huawei Technologies Co., Ltd. S12700, S5700, S6700, S7700, S9700. 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-2016-8786/ (Markdown: https://insights.sbomify.com/CVE-2016-8786/index.md)","id":"CVE-2016-8786","markdown":"https://insights.sbomify.com/CVE-2016-8786/index.md","name":"CVE-2016-8786","record":{"aliases":["GHSA-v32r-xrgh-2vx8"],"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":"Remote attackers can cause device restarts by sending malformed RSVP packets due to insufficient input validation in Huawei switches.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"s12700_firmware","vendor":"huawei"},{"product":"s5700_firmware","vendor":"huawei"},{"product":"s6700_firmware","vendor":"huawei"},{"product":"s7700_firmware","vendor":"huawei"},{"product":"s9700_firmware","vendor":"huawei"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Huawei S12700 V200R005C00, V200R006C00, V200R007C00, V200R008C00, S5700 V200R006C00, V200R007C00, V200R008C00, S6700 V200R008C00, S7700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00, S9700 V200R001C00, V200R002C00, V200R003C00, V200R005C00, V200R006C00, V200R007C00, V200R008C00 have a denial of service (DoS) vulnerability.
