An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-52221 in the wild and no public exploit code.\n\nAffected product: Tenda Ac6 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-2025-52221/ (Markdown: https://insights.sbomify.com/CVE-2025-52221/index.md)","id":"CVE-2025-52221","markdown":"https://insights.sbomify.com/CVE-2025-52221/index.md","name":"CVE-2025-52221","record":{"aliases":["GHSA-6qx4-cmrg-x79q"],"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 AC6 router","requires_auth":"none","summary":"A buffer overflow in the Tenda AC6 router allows attackers to execute arbitrary code or cause a denial of service via crafted parameters.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac6_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"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Tenda AC6 15.03.05.16_multi is vulnerable to Buffer Overflow in the formSetCfm function via the funcname, funcpara1, and funcpara2 parameters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2025-52221","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ac6_firmware","products":["tenda:ac6_firmware"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2025-52222"},"packages":[],"prev":{"headline":"Open redirect in n/a","id":"CVE-2025-52219"},"products":["n/a"],"published":"2026-04-08","related":[{"cvss_score":9.8,"headline":"Auth bypass in AC6 V5.0","id":"CVE-2025-27129","kev_date_added":null,"published":"2025-08-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29029","kev_date_added":null,"published":"2025-03-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29030","kev_date_added":null,"published":"2025-03-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29031","kev_date_added":null,"published":"2025-03-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-25343","kev_date_added":null,"published":"2025-02-12"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-40830","kev_date_added":null,"published":"2023-10-03"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2023-40837","kev_date_added":null,"published":"2023-08-30"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-10","vendors":["n/a"]},"summary":"A buffer overflow in the Tenda AC6 router allows attackers to execute arbitrary code or cause a denial of service via crafted parameters.","url":"https://insights.sbomify.com/CVE-2025-52221/"}
