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-2020-1818 in the wild and no public exploit code.\n\nAffected product: Huawei Ips Module 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-2020-1818/ (Markdown: https://insights.sbomify.com/CVE-2020-1818/index.md)","id":"CVE-2020-1818","markdown":"https://insights.sbomify.com/CVE-2020-1818/index.md","name":"CVE-2020-1818","record":{"aliases":["GHSA-mcxh-4gjr-cmr4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei network security","requires_auth":"none","summary":"Out-of-bounds read vulnerabilities in Huawei network devices allow attackers to disrupt service via malicious packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"ips_module_firmware","vendor":"huawei"},{"product":"ngfw_module_firmware","vendor":"huawei"},{"product":"nip6300_firmware","vendor":"huawei"},{"product":"nip6600_firmware","vendor":"huawei"},{"product":"nip6800_firmware","vendor":"huawei"},{"product":"secospace_usg6300_firmware","vendor":"huawei"},{"product":"secospace_usg6500_firmware","vendor":"huawei"},{"product":"secospace_usg6600_firmware","vendor":"huawei"},{"product":"usg6000v_firmware","vendor":"huawei"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"There are multiple out of bounds (OOB) read vulnerabilities in the implementation of the Common Open Policy Service (COPS) protocol of some Huawei products.
