An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-37721 and fix it if it is affected.\n\nWhat it is: CVE-2023-37721 is a critical memory corruption vulnerability in Tenda Fh1202 Firmware, published on 14 Jul 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-2023-37721 exists.\n\nAffected product: Tenda Fh1202 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-2023-37721/ (Markdown: https://insights.sbomify.com/CVE-2023-37721/index.md)","id":"CVE-2023-37721","markdown":"https://insights.sbomify.com/CVE-2023-37721/index.md","name":"CVE-2023-37721","record":{"aliases":["GHSA-mxr4-xcx8-5frq"],"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 router","requires_auth":"none","summary":"A stack overflow in the Tenda F1202 router allows attackers to execute arbitrary code or cause a denial of service via the page parameter.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"4g300_firmware","vendor":"tenda"},{"product":"f1202_firmware","vendor":"tenda"},{"product":"fh1202_firmware","vendor":"tenda"},{"product":"pa202_firmware","vendor":"tenda"},{"product":"pw201a_firmware","vendor":"tenda"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Tenda F1202 V1.0BR_V1.2.0.20(408), FH1202_V1.2.0.19_EN were discovered to contain a stack overflow in the page parameter in the function fromSafeMacFilter.","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-2023-37721","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:fh1202_firmware","products":["tenda:fh1202_firmware"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-37722"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-37719"},"products":["n/a"],"published":"2023-07-14","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-38929","kev_date_added":null,"published":"2023-08-07"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-37718","kev_date_added":null,"published":"2023-07-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-37722","kev_date_added":null,"published":"2023-07-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-37723","kev_date_added":null,"published":"2023-07-14"},{"cvss_score":8.8,"headline":"Tenda 4G300 sub_41E858 stack-based overflow","id":"CVE-2024-4166","kev_date_added":null,"published":"2024-04-25"},{"cvss_score":8.8,"headline":"Tenda 4G300 sub_422AA4 stack-based overflow","id":"CVE-2024-4167","kev_date_added":null,"published":"2024-04-25"}],"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":"total"},"state":"PUBLISHED","updated":"2024-10-30","vendors":["n/a"]},"summary":"A stack overflow in the Tenda F1202 router allows attackers to execute arbitrary code or cause a denial of service via the page parameter.","url":"https://insights.sbomify.com/CVE-2023-37721/"}
