An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-43867 and fix it if it is affected.\n\nWhat it is: CVE-2023-43867 is a high-severity memory corruption vulnerability in Dlink Dir-619l Firmware, published on 28 Sep 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-43867 exists.\n\nAffected product: Dlink Dir-619l 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-2023-43867/ (Markdown: https://insights.sbomify.com/CVE-2023-43867/index.md)","id":"CVE-2023-43867","markdown":"https://insights.sbomify.com/CVE-2023-43867/index.md","name":"CVE-2023-43867","record":{"aliases":["GHSA-6x3p-j7vv-4vc2"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"A buffer overflow in the D-Link DIR-619L router allows attackers to execute arbitrary code via the formSetWanL2TP function.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dir-619l_firmware","vendor":"dlink"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"D-Link DIR-619L B1 2.02 is vulnerable to Buffer Overflow via formSetWanL2TP 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":"Memory corruption in n/a","id":"CVE-2023-43867","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dlink:dir-619l_firmware","products":["dlink:dir-619l_firmware"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-43868"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-43866"},"products":["n/a"],"published":"2023-09-28","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55599","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55602","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55611","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-43869","kev_date_added":null,"published":"2023-09-28"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19319","kev_date_added":null,"published":"2023-09-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-19320","kev_date_added":null,"published":"2023-09-11"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-37791","kev_date_added":null,"published":"2023-07-17"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-23","vendors":["n/a"]},"summary":"A buffer overflow in the D-Link DIR-619L router allows attackers to execute arbitrary code via the formSetWanL2TP function.","url":"https://insights.sbomify.com/CVE-2023-43867/"}
