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-2022-25427 in the wild and no public exploit code.\n\nAffected product: Tenda Ac9 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-2022-25427/ (Markdown: https://insights.sbomify.com/CVE-2022-25427/index.md)","id":"CVE-2022-25427","markdown":"https://insights.sbomify.com/CVE-2022-25427/index.md","name":"CVE-2022-25427","record":{"aliases":["GHSA-rmm3-6m9q-fwfm"],"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 AC9 router","requires_auth":"none","summary":"A stack overflow in the Tenda AC9 router allows attackers to execute arbitrary code or cause a denial of service via the schedendtime parameter.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac9_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 AC9 v15.03.2.21 was discovered to contain a stack overflow via the schedendtime parameter in the openSchedWifi function.","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-2022-25427","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ac9_firmware","products":["tenda:ac9_firmware"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2022-25428"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2022-25420"},"products":["n/a"],"published":"2022-03-18","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-45042","kev_date_added":null,"published":"2025-05-05"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-44872","kev_date_added":null,"published":"2025-05-02"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2025-44877","kev_date_added":null,"published":"2025-05-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45427","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45428","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-45429","kev_date_added":null,"published":"2025-04-23"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-29384","kev_date_added":null,"published":"2025-03-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"A stack overflow in the Tenda AC9 router allows attackers to execute arbitrary code or cause a denial of service via the schedendtime parameter.","url":"https://insights.sbomify.com/CVE-2022-25427/"}
