An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-0637 in the wild and no public exploit code.\n\nAffected product: NEC Corporation HC100RC. 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-2018-0637/ (Markdown: https://insights.sbomify.com/CVE-2018-0637/index.md)","id":"CVE-2018-0637","markdown":"https://insights.sbomify.com/CVE-2018-0637/index.md","name":"CVE-2018-0637","record":{"aliases":["GHSA-wgm4-m2jm-jg3m"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NEC Aterm router","requires_auth":"high_privilege","summary":"An administrator can execute arbitrary OS commands on NEC Aterm HC100RC routers via the export.cgi encKey parameter.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"aterm_hc100rc_firmware","vendor":"nec"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Aterm HC100RC Ver1.0.1 and earlier allows attacker with administrator rights to execute arbitrary OS commands via export.cgi encKey parameter.","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 HC100RC","id":"CVE-2018-0637","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in HC100RC","id":"CVE-2018-0638"},"packages":[],"prev":{"headline":"Command injection in HC100RC","id":"CVE-2018-0636"},"products":["HC100RC"],"published":"2019-01-09","related":[{"cvss_score":7.2,"headline":"Command injection in HC100RC","id":"CVE-2018-0634","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.2,"headline":"Command injection in HC100RC","id":"CVE-2018-0635","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.2,"headline":"Command injection in HC100RC","id":"CVE-2018-0636","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.2,"headline":"Command injection in HC100RC","id":"CVE-2018-0638","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.2,"headline":"Command injection in HC100RC","id":"CVE-2018-0639","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.2,"headline":"Memory corruption in HC100RC","id":"CVE-2018-0640","kev_date_added":null,"published":"2019-01-09"}],"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":"2024-08-05","vendors":["NEC Corporation"]},"summary":"An administrator can execute arbitrary OS commands on NEC Aterm HC100RC routers via the export.cgi encKey parameter.","url":"https://insights.sbomify.com/CVE-2018-0637/"}
