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-2022-22687 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-2022-22687/ (Markdown: https://insights.sbomify.com/CVE-2022-22687/index.md)","id":"CVE-2022-22687","markdown":"https://insights.sbomify.com/CVE-2022-22687/index.md","name":"CVE-2022-22687","record":{"aliases":["GHSA-3h67-wjhc-r8m7"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Synology NAS OS","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a buffer overflow in the authentication functionality of Synology DiskStation Manager.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"diskstation_manager","vendor":"synology"},{"product":"diskstation_manager_unified_controller","vendor":"synology"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer copy without checking size of input ('Classic Buffer Overflow') vulnerability in Authentication functionality in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows remote attackers 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":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-22687","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:diskstation_manager","products":["synology:diskstation_manager"],"type":"memory_corruption","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in DiskStation Manager (DSM)","id":"CVE-2022-22688"},"packages":[],"prev":{"headline":"Cross-site request forgery in Synology Calendar","id":"CVE-2022-22686"},"products":["DiskStation Manager (DSM)"],"published":"2022-03-25","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":"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 execute arbitrary code via a buffer overflow in the authentication functionality of Synology DiskStation Manager.","url":"https://insights.sbomify.com/CVE-2022-22687/"}
