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-2025-57639 exists.\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-2025-57639/ (Markdown: https://insights.sbomify.com/CVE-2025-57639/index.md)","id":"CVE-2025-57639","markdown":"https://insights.sbomify.com/CVE-2025-57639/index.md","name":"CVE-2025-57639","record":{"aliases":["GHSA-9745-w7f4-f37c"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Tenda AC9 router","requires_auth":"none","summary":"Attackers can execute arbitrary OS commands on Tenda AC9 routers via the usb.samba.guest.user parameter in the httpd service.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ac9_firmware","vendor":"tenda"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"OS Command injection vulnerability in Tenda AC9 1.0 was discovered to contain a command injection vulnerability via the usb.samba.guest.user parameter in the formSetSambaConf function of the httpd file.","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":"Command injection in n/a","id":"CVE-2025-57639","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tenda:ac9_firmware","products":["tenda:ac9_firmware"],"type":"command_injection","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2025-57642"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2025-57638"},"products":["n/a"],"published":"2025-09-23","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":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-09-24","vendors":["n/a"]},"summary":"Attackers can execute arbitrary OS commands on Tenda AC9 routers via the usb.samba.guest.user parameter in the httpd service.","url":"https://insights.sbomify.com/CVE-2025-57639/"}
