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-2020-5634 in the wild and no public exploit code.\n\nAffected product: ELECOM LAN routers. 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-2020-5634/ (Markdown: https://insights.sbomify.com/CVE-2020-5634/index.md)","id":"CVE-2020-5634","markdown":"https://insights.sbomify.com/CVE-2020-5634/index.md","name":"CVE-2020-5634","record":{"aliases":["GHSA-jpxf-7694-4wcf"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ELECOM LAN router","requires_auth":"none","summary":"Attackers on the same network can execute arbitrary OS commands with root privileges on ELECOM LAN routers.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"wrc-1167gst2_firmware","vendor":"elecom"},{"product":"wrc-1750gst2_firmware","vendor":"elecom"},{"product":"wrc-1900gst2_firmware","vendor":"elecom"},{"product":"wrc-2533gst2_firmware","vendor":"elecom"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"ELECOM LAN routers (WRC-2533GST2 firmware versions prior to v1.14, WRC-1900GST2 firmware versions prior to v1.14, WRC-1750GST2 firmware versions prior to v1.14, and WRC-1167GST2 firmware versions prior to v1.10) allow an attacker on the same network segment to execute arbitrary OS commands with a root privilege via unspecified vectors.","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":"Command injection in ELECOM LAN routers","id":"CVE-2020-5634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in Aterm SA3500G","id":"CVE-2020-5635"},"packages":[],"prev":{"headline":"Auth bypass in Multiple NEC products where Baseboard Management Controller (BMC) firmware Rev1.09 and earlier is applied","id":"CVE-2020-5633"},"products":["ELECOM LAN routers"],"published":"2020-10-06","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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["ELECOM CO.,LTD."]},"summary":"Attackers on the same network can execute arbitrary OS commands with root privileges on ELECOM LAN routers.","url":"https://insights.sbomify.com/CVE-2020-5634/"}
