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-2023-39784 exists.\n\nAffected product: Tenda Ac8 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-2023-39784/ (Markdown: https://insights.sbomify.com/CVE-2023-39784/index.md)","id":"CVE-2023-39784","markdown":"https://insights.sbomify.com/CVE-2023-39784/index.md","name":"CVE-2023-39784","record":{"aliases":["GHSA-p98h-f733-2xp5"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AC8V4 router","requires_auth":"none","summary":"A stack overflow in the save_virtualser_data function allows attackers to execute arbitrary code or cause denial of service on Tenda AC8V4 routers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac8_firmware","vendor":"tenda"}],"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":"Tenda AC8V4 V16.03.34.06 was discovered to contain a stack overflow via the list parameter in the save_virtualser_data 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-2023-39784","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ac8_firmware","products":["tenda:ac8_firmware"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-39785"},"packages":[],"prev":{"headline":"ASUS RT-AX55 Routers OS Command Injection","id":"CVE-2023-39780"},"products":["n/a"],"published":"2023-08-21","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29100","kev_date_added":null,"published":"2025-03-24"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-25663","kev_date_added":null,"published":"2025-02-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-25664","kev_date_added":null,"published":"2025-02-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-25667","kev_date_added":null,"published":"2025-02-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-25668","kev_date_added":null,"published":"2025-02-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-46652","kev_date_added":null,"published":"2024-09-20"},{"cvss_score":9.8,"headline":"Tenda AC8 formSetDeviceName stack-based overflow","id":"CVE-2023-4744","kev_date_added":null,"published":"2023-09-03"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"A stack overflow in the save_virtualser_data function allows attackers to execute arbitrary code or cause denial of service on Tenda AC8V4 routers.","url":"https://insights.sbomify.com/CVE-2023-39784/"}
