An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-40874 and fix it if it is affected.\n\nWhat it is: CVE-2022-40874 is a high-severity memory corruption vulnerability in Tenda Ax1803 Firmware, published on 27 Oct 2022. 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-2022-40874 exists.\n\nAffected product: Tenda Ax1803 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-2022-40874/ (Markdown: https://insights.sbomify.com/CVE-2022-40874/index.md)","id":"CVE-2022-40874","markdown":"https://insights.sbomify.com/CVE-2022-40874/index.md","name":"CVE-2022-40874","record":{"aliases":["GHSA-qjm8-ccv3-g62v"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AX1803 router","requires_auth":"none","summary":"A heap overflow in the Tenda AX1803 router allows attackers to cause a denial of service via a crafted HTTP request.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ax1803_firmware","vendor":"tenda"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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 AX1803 v1.0.0.1 was discovered to contain a heap overflow vulnerability in the GetParentControlInfo function, which can cause a denial of service attack through a carefully constructed http request.","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-2022-40874","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ax1803_firmware","products":["tenda:ax1803_firmware"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2022-40875"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2022-40872"},"products":["n/a"],"published":"2022-10-27","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2024-30620","kev_date_added":null,"published":"2024-04-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51952","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51953","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51954","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51956","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51957","kev_date_added":null,"published":"2024-01-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-51958","kev_date_added":null,"published":"2024-01-10"}],"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":"2025-05-07","vendors":["n/a"]},"summary":"A heap overflow in the Tenda AX1803 router allows attackers to cause a denial of service via a crafted HTTP request.","url":"https://insights.sbomify.com/CVE-2022-40874/"}
