An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-18489 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-18489/ (Markdown: https://insights.sbomify.com/CVE-2018-18489/index.md)","id":"CVE-2018-18489","markdown":"https://insights.sbomify.com/CVE-2018-18489/index.md","name":"CVE-2018-18489","record":{"aliases":["GHSA-6cv2-23h8-f75x"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"TP-LINK router","requires_auth":"high_privilege","summary":"Remote attackers can cause denial of service on TP-LINK WR840N routers by sending oversized packets to the diagnostic ping feature.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wr840n_firmware","vendor":"tp-link"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"The ping feature in the Diagnostic functionality on TP-LINK WR840N v2 Firmware 3.16.9 Build 150701 Rel.51516n devices allows remote attackers to cause a denial of service (HTTP service termination) by modifying the packet size to be higher than the UI limit of 1472.","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":"Denial of service in n/a","id":"CVE-2018-18489","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Firefox","id":"CVE-2018-18492"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2018-18488"},"products":["n/a"],"published":"2019-04-16","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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service on TP-LINK WR840N routers by sending oversized packets to the diagnostic ping feature.","url":"https://insights.sbomify.com/CVE-2018-18489/"}
