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-2018-7920 in the wild and no public exploit code.\n\nAffected product: Huawei Ar3200 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-2018-7920/ (Markdown: https://insights.sbomify.com/CVE-2018-7920/index.md)","id":"CVE-2018-7920","markdown":"https://insights.sbomify.com/CVE-2018-7920/index.md","name":"CVE-2018-7920","record":{"aliases":["GHSA-vmrh-mj92-7wj2"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Huawei AR router","requires_auth":"none","summary":"Remote attackers can exhaust socket resources on Huawei AR routers via TCP messages, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"ar1200_firmware","vendor":"huawei"},{"product":"ar160_firmware","vendor":"huawei"},{"product":"ar200_firmware","vendor":"huawei"},{"product":"ar2200_firmware","vendor":"huawei"},{"product":"ar3200_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-400","name":"Uncontrolled Resource Consumption"}],"description":"Huawei AR1200 V200R006C10SPC300, AR160 V200R006C10SPC300, AR200 V200R006C10SPC300, AR2200 V200R006C10SPC300, AR3200 V200R006C10SPC300 devices have an improper resource management vulnerability.
