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-2021-45837 exists.\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-2021-45837/ (Markdown: https://insights.sbomify.com/CVE-2021-45837/index.md)","id":"CVE-2021-45837","markdown":"https://insights.sbomify.com/CVE-2021-45837/index.md","name":"CVE-2021-45837","record":{"aliases":["GHSA-46j4-7889-xgxc"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"NAS operating system","requires_auth":"none","summary":"Attackers can execute arbitrary commands as root on Terramaster NAS devices via crafted input to a specific endpoint.","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":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":[],"description":"It is possible to execute arbitrary commands as root in Terramaster F4-210, F2-210 TOS 4.2.X (4.2.15-2107141517) by sending a specifically crafted input to /tos/index.php?app/del.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-12-24","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2021-12-24","kind":"metasploit","ref":"exploit/linux/http/terramaster_unauth_rce_cve_2021_45837","stars":null,"title":"TerraMaster TOS 4.2.15 or lower - RCE chain from unauthenticated to root via session crafting."}],"tier":"weaponised"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2021-45837","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-45839"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-45836"},"products":["n/a"],"published":"2022-04-25","related":[{"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":8.8,"headline":"Command injection in n/a","id":"CVE-2021-45836","kev_date_added":null,"published":"2022-04-25"},{"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary commands as root on Terramaster NAS devices via crafted input to a specific endpoint.","url":"https://insights.sbomify.com/CVE-2021-45837/"}
