Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43928 in the wild and no public exploit code.\n\nAffected product: Synology Mail Station. 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-2021-43928/ (Markdown: https://insights.sbomify.com/CVE-2021-43928/index.md)","id":"CVE-2021-43928","markdown":"https://insights.sbomify.com/CVE-2021-43928/index.md","name":"CVE-2021-43928","record":{"aliases":["GHSA-xcmm-3w7w-cqq9"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Mail Station","requires_auth":"low_privilege","summary":"Remote authenticated users can execute arbitrary OS commands in Synology Mail Station via improper neutralization of special elements.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"mail_station","vendor":"synology"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"Improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability in mail sending and receiving component in Synology Mail Station before 20211105-10315 allows remote authenticated users to execute arbitrary commands via unspecified vectors.","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 Mail Station","id":"CVE-2021-43928","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":"Cross-site scripting in DiskStation Manager (DSM)","id":"CVE-2021-43929"},"packages":[],"prev":{"headline":"SQL injection in DiskStation Manager (DSM)","id":"CVE-2021-43927"},"products":["Mail Station"],"published":"2022-02-07","related":[],"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":"2024-09-17","vendors":["Synology"]},"summary":"Remote authenticated users can execute arbitrary OS commands in Synology Mail Station via improper neutralization of special elements.","url":"https://insights.sbomify.com/CVE-2021-43928/"}
