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-2020-26143 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-26143/ (Markdown: https://insights.sbomify.com/CVE-2020-26143/index.md)","id":"CVE-2020-26143","markdown":"https://insights.sbomify.com/CVE-2020-26143/index.md","name":"CVE-2020-26143","record":{"aliases":["GHSA-c49c-jx24-458g","ROOT-OS-UBUNTU-2204-CVE-2020-26143","UBUNTU-CVE-2020-26143"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Wi-Fi driver","requires_auth":"none","summary":"Attackers can inject arbitrary data frames into protected Wi-Fi networks by exploiting a flaw in the ALFA Windows 10 driver's handling of fragmented plaintext frames.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"awus036h_firmware","vendor":"alfa"},{"product":"c-65_firmware","vendor":"arista"},{"product":"c-75_firmware","vendor":"arista"},{"product":"o-90_firmware","vendor":"arista"},{"product":"w-68_firmware","vendor":"arista"},{"product":"scalance_w700_ieee_802.11n_firmware","vendor":"siemens"}],"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:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH.
