It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-46740 and fix it if it is affected.\n\nWhat it is: CVE-2022-46740 is a medium-severity denial of service vulnerability in Huawei WS7100-20, published on 28 Dec 2022. 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-2022-46740 in the wild and no public exploit code.\n\nAffected product: Huawei WS7100-20. 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-2022-46740/ (Markdown: https://insights.sbomify.com/CVE-2022-46740/index.md)","id":"CVE-2022-46740","markdown":"https://insights.sbomify.com/CVE-2022-46740/index.md","name":"CVE-2022-46740","record":{"aliases":["GHSA-8x84-9m3r-fv77"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Huawei smart router","requires_auth":"none","summary":"Attackers can cause a denial of service on Huawei WS7100-20 routers via the Wi-Fi module, disrupting network availability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"huawei","cpe":[{"product":"ws7100-20_firmware","vendor":"huawei"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","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-400","name":"Uncontrolled Resource Consumption"}],"description":"There is a denial of service vulnerability in the Wi-Fi module of the HUAWEI WS7100-20 Smart WiFi Router.Successful exploit could cause a denial of service (DoS) condition.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in WS7100-20","id":"CVE-2022-46740","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"PaddlePaddle Out-of-bounds Read vulnerability","id":"CVE-2022-46741"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it is Unused","id":"CVE-2022-46739"},"products":["WS7100-20"],"published":"2022-12-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-11","vendors":["Huawei"]},"summary":"Attackers can cause a denial of service on Huawei WS7100-20 routers via the Wi-Fi module, disrupting network availability.","url":"https://insights.sbomify.com/CVE-2022-46740/"}
