LAN-W300N/P, published on 16 Nov 2023. 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-2023-43757 in the wild and no public exploit code.\n\nAffected product: ELECOM CO.,LTD. LAN-W300N/P. 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-2023-43757/ (Markdown: https://insights.sbomify.com/CVE-2023-43757/index.md)","id":"CVE-2023-43757","markdown":"https://insights.sbomify.com/CVE-2023-43757/index.md","name":"CVE-2023-43757","record":{"aliases":["GHSA-hjvf-vwpv-9g29"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Wireless router","requires_auth":"none","summary":"An attacker can guess weak wireless encryption keys to intercept network traffic on affected ELECOM and LOGITEC routers.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"lan-w300n\\/p_firmware","vendor":"elecom"},{"product":"lan-w300n\\/rs_firmware","vendor":"elecom"},{"product":"lan-w301nr_firmware","vendor":"elecom"},{"product":"lan-wh300n\\/dgp_firmware","vendor":"elecom"},{"product":"lan-wh300ndgpe_firmware","vendor":"elecom"},{"product":"wrc-1167ghbk2_firmware","vendor":"elecom"},{"product":"wrc-1167ghbk_firmware","vendor":"elecom"},{"product":"wrc-1750ghbk-e_firmware","vendor":"elecom"},{"product":"wrc-1750ghbk2-i_firmware","vendor":"elecom"},{"product":"wrc-1750ghbk_firmware","vendor":"elecom"},{"product":"wrc-2533ghbk-i_firmware","vendor":"elecom"},{"product":"wrc-2533ghbk2-t_firmware","vendor":"elecom"},{"product":"wrc-300febk_firmware","vendor":"elecom"},{"product":"wrc-300ghbk2-i_firmware","vendor":"elecom"},{"product":"wrc-300ghbk_firmware","vendor":"elecom"},{"product":"wrc-733febk_firmware","vendor":"elecom"},{"product":"wrc-733ghbk-c_firmware","vendor":"elecom"},{"product":"wrc-733ghbk-i_firmware","vendor":"elecom"},{"product":"wrc-733ghbk_firmware","vendor":"elecom"},{"product":"wrc-f1167acf_firmware","vendor":"elecom"},{"product":"wrc-f300nf_firmware","vendor":"elecom"},{"product":"wrh-150bk_firmware","vendor":"elecom"},{"product":"wrh-150wh_firmware","vendor":"elecom"},{"product":"wrh-300bk-s_firmware","vendor":"elecom"},{"product":"wrh-300bk2-s_firmware","vendor":"elecom"},{"product":"wrh-300bk_firmware","vendor":"elecom"},{"product":"wrh-300rd_firmware","vendor":"elecom"},{"product":"wrh-300sv_firmware","vendor":"elecom"},{"product":"wrh-300wh-h_firmware","vendor":"elecom"},{"product":"wrh-300wh-s_firmware","vendor":"elecom"},{"product":"wrh-300wh2-s_firmware","vendor":"elecom"},{"product":"wrh-300wh_firmware","vendor":"elecom"},{"product":"wrh-h300bk_firmware","vendor":"elecom"},{"product":"wrh-h300wh_firmware","vendor":"elecom"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"Inadequate encryption strength vulnerability in multiple routers provided by ELECOM CO.,LTD. and LOGITEC CORPORATION allows a network-adjacent unauthenticated attacker to guess the encryption key used for wireless LAN communication and intercept the communication.
