Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34810 in the wild and no public exploit code.\n\nAffected product: Synology Download 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-2021-34810/ (Markdown: https://insights.sbomify.com/CVE-2021-34810/index.md)","id":"CVE-2021-34810","markdown":"https://insights.sbomify.com/CVE-2021-34810/index.md","name":"CVE-2021-34810","record":{"aliases":["GHSA-473c-wh3w-ppx8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology Download Station","requires_auth":"low_privilege","summary":"Remote authenticated users can execute arbitrary code due to improper privilege management in Synology Download Station.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"download_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-269","name":"Improper Privilege Management"}],"description":"Improper privilege management vulnerability in cgi component in Synology Download Station before 3.8.16-3566 allows remote authenticated users to execute arbitrary code 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":"Privilege escalation in Download Station","id":"CVE-2021-34810","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Server-side request forgery in Download Station","id":"CVE-2021-34811"},"packages":[],"prev":{"headline":"Command injection in Download Station","id":"CVE-2021-34809"},"products":["Download Station"],"published":"2021-06-18","related":[{"cvss_score":9.9,"headline":"Command injection in Download Station","id":"CVE-2021-34809","kev_date_added":null,"published":"2021-06-18"},{"cvss_score":7.8,"headline":"File upload in Synology Download Station","id":"CVE-2017-11156","kev_date_added":null,"published":"2017-08-14"},{"cvss_score":7.7,"headline":"Server-side request forgery in Synology Download Station","id":"CVE-2021-33184","kev_date_added":null,"published":"2021-06-01"},{"cvss_score":6.5,"headline":"Server-side request forgery in Synology Download Station","id":"CVE-2017-11149","kev_date_added":null,"published":"2017-08-14"},{"cvss_score":5,"headline":"Server-side request forgery in Download Station","id":"CVE-2021-34811","kev_date_added":null,"published":"2021-06-18"},{"cvss_score":4.3,"headline":"Cross-site scripting in n/a","id":"CVE-2015-6909","kev_date_added":null,"published":"2015-09-11"}],"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":"2024-09-16","vendors":["Synology"]},"summary":"Remote authenticated users can execute arbitrary code due to improper privilege management in Synology Download Station.","url":"https://insights.sbomify.com/CVE-2021-34810/"}
