An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1883 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-2020-1883/ (Markdown: https://insights.sbomify.com/CVE-2020-1883/index.md)","id":"CVE-2020-1883","markdown":"https://insights.sbomify.com/CVE-2020-1883/index.md","name":"CVE-2020-1883","record":{"aliases":["GHSA-f9q6-fjfw-vhwc"],"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":"high_privilege","summary":"High-privilege attackers can cause service abnormalities in Huawei network devices through a memory leak triggered by specific operations.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"nip6800_firmware","vendor":"huawei"},{"product":"secospace_usg6600_firmware","vendor":"huawei"},{"product":"usg9500_firmware","vendor":"huawei"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"Huawei products NIP6800;Secospace USG6600;USG9500 have a memory leak vulnerability.
