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-2025-69766 exists.\n\nAffected product: Tenda Ax3 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-2025-69766/ (Markdown: https://insights.sbomify.com/CVE-2025-69766/index.md)","id":"CVE-2025-69766","markdown":"https://insights.sbomify.com/CVE-2025-69766/index.md","name":"CVE-2025-69766","record":{"aliases":["GHSA-2w96-8922-g8xr"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AX3 router","requires_auth":"none","summary":"A stack-based buffer overflow in the Tenda AX3 router allows remote attackers to execute arbitrary code via the formGetIptv function.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ax3_firmware","vendor":"tenda"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","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-121","name":"Stack-based Buffer Overflow"}],"description":"Tenda AX3 firmware v16.03.12.11 contains a stack-based buffer overflow in the formGetIptv function due to improper handling of the citytag stack buffer, which may result in memory corruption and remote code execution.","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-2025-69766","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ax3_firmware","products":["tenda:ax3_firmware"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2025-69768"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2025-69765"},"products":["n/a"],"published":"2026-01-21","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-69764","kev_date_added":null,"published":"2026-01-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-69762","kev_date_added":null,"published":"2026-01-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-69763","kev_date_added":null,"published":"2026-01-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55603","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55605","kev_date_added":null,"published":"2025-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2025-55606","kev_date_added":null,"published":"2025-08-22"}],"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":"2026-01-22","vendors":["n/a"]},"summary":"A stack-based buffer overflow in the Tenda AX3 router allows remote attackers to execute arbitrary code via the formGetIptv function.","url":"https://insights.sbomify.com/CVE-2025-69766/"}
