An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-29083 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-2021-29083/ (Markdown: https://insights.sbomify.com/CVE-2021-29083/index.md)","id":"CVE-2021-29083","markdown":"https://insights.sbomify.com/CVE-2021-29083/index.md","name":"CVE-2021-29083","record":{"aliases":["GHSA-cjg6-frrp-p7cp"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology NAS OS","requires_auth":"high_privilege","summary":"Remote authenticated users can execute arbitrary code via OS command injection in the PPPoE network module of Synology DSM.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"diskstation_manager","vendor":"synology"}],"cvss":{"score":7.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/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 in SYNO.Core.Network.PPPoE in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows remote authenticated users to execute arbitrary code via realname parameter.","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 Synology DiskStation Manager (DSM)","id":"CVE-2021-29083","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:diskstation_manager","products":["synology:diskstation_manager"],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in DiskStation Manager (DSM)","id":"CVE-2021-29084"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-29082"},"products":["Synology DiskStation Manager (DSM)"],"published":"2021-04-01","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":"2024-09-17","vendors":["Synology"]},"summary":"Remote authenticated users can execute arbitrary code via OS command injection in the PPPoE network module of Synology DSM.","url":"https://insights.sbomify.com/CVE-2021-29083/"}
