It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-30840 exists.\n\nAffected product: Tenda Ac15 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-2024-30840/ (Markdown: https://insights.sbomify.com/CVE-2024-30840/index.md)","id":"CVE-2024-30840","markdown":"https://insights.sbomify.com/CVE-2024-30840/index.md","name":"CVE-2024-30840","record":{"aliases":["GHSA-j9hf-h25p-vw62"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Tenda AC15 router","requires_auth":"none","summary":"Attackers can cause a denial of service on Tenda AC15 routers via a stack overflow in the DHCP client function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac15_firmware","vendor":"tenda"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A Stack Overflow vulnerability in Tenda AC15 v15.03.05.18 allows attackers to cause a denial of service via the LISTEN parameter in the fromDhcpListClient function.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2024-30840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ac15_firmware","products":["tenda:ac15_firmware"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2024-30845"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2024-30809"},"products":["n/a"],"published":"2024-04-15","related":[{"cvss_score":9.8,"headline":"Tenda AC1900 Router AC15 Model Remote Code Execution","id":"CVE-2020-10987","kev_date_added":"2021-11-03","published":"2020-07-13"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2026-24103","kev_date_added":null,"published":"2026-03-03"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2026-24101","kev_date_added":null,"published":"2026-03-02"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2026-24105","kev_date_added":null,"published":"2026-03-02"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2025-63666","kev_date_added":null,"published":"2025-11-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29462","kev_date_added":null,"published":"2025-04-03"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-25632","kev_date_added":null,"published":"2025-03-05"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-15","vendors":["n/a"]},"summary":"Attackers can cause a denial of service on Tenda AC15 routers via a stack overflow in the DHCP client function.","url":"https://insights.sbomify.com/CVE-2024-30840/"}
