Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-40798 exists.\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-2023-40798/ (Markdown: https://insights.sbomify.com/CVE-2023-40798/index.md)","id":"CVE-2023-40798","markdown":"https://insights.sbomify.com/CVE-2023-40798/index.md","name":"CVE-2023-40798","record":{"aliases":["GHSA-mmrw-88mx-92rq"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AC23 router","requires_auth":"low_privilege","summary":"An authenticated attacker can trigger a stack overflow in Tenda AC23 routers via specific form functions, potentially leading to code execution.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac23_firmware","vendor":"tenda"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Tenda AC23 v16.03.07.45_cn, the formSetIPv6status and formGetWanParameter functions do not authenticate user input parameters, resulting in a post-authentication stack overflow vulnerability.","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-2023-40798","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-40799"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-40797"},"products":["n/a"],"published":"2023-08-25","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-40799","kev_date_added":null,"published":"2023-08-25"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43101","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43102","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43103","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43104","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43105","kev_date_added":null,"published":"2022-11-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-43106","kev_date_added":null,"published":"2022-11-03"}],"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":"total"},"state":"PUBLISHED","updated":"2024-10-02","vendors":["n/a"]},"summary":"An authenticated attacker can trigger a stack overflow in Tenda AC23 routers via specific form functions, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2023-40798/"}
