An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-29087 in the wild and no public exploit code.\n\nAffected product: Synology Diskstation Manager. 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-2021-29087/ (Markdown: https://insights.sbomify.com/CVE-2021-29087/index.md)","id":"CVE-2021-29087","markdown":"https://insights.sbomify.com/CVE-2021-29087/index.md","name":"CVE-2021-29087","record":{"aliases":["GHSA-9977-6673-28cw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology NAS OS","requires_auth":"none","summary":"Remote attackers can write arbitrary files via path traversal in the webapi component of Synology DiskStation Manager.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"diskstation_manager","vendor":"synology"},{"product":"diskstation_manager_unified_controller","vendor":"synology"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in webapi component in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows remote attackers to write arbitrary files 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":"Path traversal in DiskStation Manager (DSM)","id":"CVE-2021-29087","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:diskstation_manager","products":["synology:diskstation_manager"],"type":"path_traversal","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Synology DiskStation Manager (DSM)","id":"CVE-2021-29088"},"packages":[],"prev":{"headline":"Information disclosure in DiskStation Manager (DSM)","id":"CVE-2021-29086"},"products":["DiskStation Manager (DSM)"],"published":"2021-06-23","related":[{"cvss_score":10,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-27624","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-27625","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Race condition in DiskStation Manager (DSM)","id":"CVE-2022-27626","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Path traversal in n/a","id":"CVE-2013-6955","kev_date_added":null,"published":"2014-01-09"},{"cvss_score":9.8,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-22687","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":9.8,"headline":"Use after free in DiskStation Manager (DSM)","id":"CVE-2021-27649","kev_date_added":null,"published":"2021-06-23"},{"cvss_score":9.8,"headline":"Race condition in Synology DiskStation Manager (DSM)","id":"CVE-2021-26569","kev_date_added":null,"published":"2021-03-12"}],"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 attackers can write arbitrary files via path traversal in the webapi component of Synology DiskStation Manager.","url":"https://insights.sbomify.com/CVE-2021-29087/"}
