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-2020-5637 in the wild and no public exploit code.\n\nAffected product: NEC Corporation Aterm SA3500G. 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-2020-5637/ (Markdown: https://insights.sbomify.com/CVE-2020-5637/index.md)","id":"CVE-2020-5637","markdown":"https://insights.sbomify.com/CVE-2020-5637/index.md","name":"CVE-2020-5637","record":{"aliases":["GHSA-446c-h2fq-7hw2"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NEC Aterm router","requires_auth":"high_privilege","summary":"An attacker with administrative privileges can execute malicious programs on NEC Aterm SA3500G routers due to improper integrity check validation.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"aterm_sa3500g_firmware","vendor":"necplatforms"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"}],"description":"Improper validation of integrity check value vulnerability in Aterm SA3500G firmware versions prior to Ver. 3.5.9 allows an attacker with an administrative privilege to execute a malicious program.","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":"Code injection in Aterm SA3500G","id":"CVE-2020-5637","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2020"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in desknet's NEO","id":"CVE-2020-5638"},"packages":[],"prev":{"headline":"Command injection in Aterm SA3500G","id":"CVE-2020-5636"},"products":["Aterm SA3500G"],"published":"2020-12-14","related":[{"cvss_score":8.8,"headline":"Command injection in Aterm SA3500G","id":"CVE-2020-5635","kev_date_added":null,"published":"2020-12-14"},{"cvss_score":6.8,"headline":"Command injection in Aterm SA3500G","id":"CVE-2020-5636","kev_date_added":null,"published":"2020-12-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["NEC Corporation"]},"summary":"An attacker with administrative privileges can execute malicious programs on NEC Aterm SA3500G routers due to improper integrity check validation.","url":"https://insights.sbomify.com/CVE-2020-5637/"}
