It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1866 in the wild and no public exploit code.\n\nAffected product: Huawei Nip6800 Firmware. 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-2020-1866/ (Markdown: https://insights.sbomify.com/CVE-2020-1866/index.md)","id":"CVE-2020-1866","markdown":"https://insights.sbomify.com/CVE-2020-1866/index.md","name":"CVE-2020-1866","record":{"aliases":["GHSA-xf3h-cpcr-5vv3"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei network devices","requires_auth":"none","summary":"Attackers can cause service disruption by sending crafted DHCP messages that trigger an out-of-bounds read in Huawei network devices.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"nip6800_firmware","vendor":"huawei"},{"product":"s12700_firmware","vendor":"huawei"},{"product":"s2700_firmware","vendor":"huawei"},{"product":"s5700_firmware","vendor":"huawei"},{"product":"s6700_firmware","vendor":"huawei"},{"product":"s7700_firmware","vendor":"huawei"},{"product":"s9700_firmware","vendor":"huawei"},{"product":"secospace_usg6600_firmware","vendor":"huawei"},{"product":"usg9500_firmware","vendor":"huawei"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"There is an out-of-bounds read vulnerability in several products.
