It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-21117 and fix it if it is affected.\n\nWhat it is: CVE-2018-21117 is a high-severity command injection vulnerability in Netgear Xr500 Firmware, published on 22 Apr 2020. 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-2018-21117 in the wild and no public exploit code.\n\nAffected product: Netgear Xr500 Firmware. 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-2018-21117/ (Markdown: https://insights.sbomify.com/CVE-2018-21117/index.md)","id":"CVE-2018-21117","markdown":"https://insights.sbomify.com/CVE-2018-21117/index.md","name":"CVE-2018-21117","record":{"aliases":["GHSA-xprj-64cf-h29h"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NETGEAR router","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code on NETGEAR XR500 routers via the traceroute handler.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xr500_firmware","vendor":"netgear"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AC:L/AV:A/A:H/C:H/I:H/PR:N/S:U/UI:N","version":"3.0"},"cwes":[],"description":"NETGEAR XR500 devices before 2.3.2.32 are affected by remote code execution by unauthenticated attackers via the traceroute handler.","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 n/a","id":"CVE-2018-21117","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"netgear:xr500_firmware","products":["netgear:xr500_firmware"],"type":"command_injection","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in n/a","id":"CVE-2018-21118"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2018-21116"},"products":["n/a"],"published":"2020-04-22","related":[{"cvss_score":8.8,"headline":"Other in n/a","id":"CVE-2018-21115","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":8.8,"headline":"Other in n/a","id":"CVE-2018-21116","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":8.8,"headline":"Auth bypass in n/a","id":"CVE-2018-21118","kev_date_added":null,"published":"2020-04-22"},{"cvss_score":7.3,"headline":"Command injection in n/a","id":"CVE-2019-20655","kev_date_added":null,"published":"2020-04-15"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Unauthenticated attackers can execute arbitrary code on NETGEAR XR500 routers via the traceroute handler.","url":"https://insights.sbomify.com/CVE-2018-21117/"}
