Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-45836 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-45836/ (Markdown: https://insights.sbomify.com/CVE-2021-45836/index.md)","id":"CVE-2021-45836","markdown":"https://insights.sbomify.com/CVE-2021-45836/index.md","name":"CVE-2021-45836","record":{"aliases":["GHSA-g2h5-m8r4-v3h9"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"NAS operating system","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary root commands via crafted input in the hand_app endpoint of Terramaster NAS devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tos","vendor":"terra-master"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"An authenticated attacker can execute arbitrary commands as root in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) by injecting a maliciously crafted input in the request through /tos/index.php?app/hand_app.","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":"Command injection in n/a","id":"CVE-2021-45836","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in n/a","id":"CVE-2021-45837"},"packages":[],"prev":{"headline":"File upload in n/a","id":"CVE-2021-45835"},"products":["n/a"],"published":"2022-04-25","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-45837","kev_date_added":null,"published":"2022-04-25"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-45840","kev_date_added":null,"published":"2022-04-25"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-15568","kev_date_added":null,"published":"2021-01-30"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-28187","kev_date_added":null,"published":"2020-12-24"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-28188","kev_date_added":null,"published":"2020-12-24"},{"cvss_score":8.1,"headline":"Auth bypass in n/a","id":"CVE-2021-45841","kev_date_added":null,"published":"2022-04-25"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Authenticated attackers can execute arbitrary root commands via crafted input in the hand_app endpoint of Terramaster NAS devices.","url":"https://insights.sbomify.com/CVE-2021-45836/"}
