Cybozu Remote Service, published on 13 Oct 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20804 in the wild and no public exploit code.\n\nAffected product: Cybozu, Inc. Cybozu Remote Service. 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-2021-20804/ (Markdown: https://insights.sbomify.com/CVE-2021-20804/index.md)","id":"CVE-2021-20804","markdown":"https://insights.sbomify.com/CVE-2021-20804/index.md","name":"CVE-2021-20804","record":{"aliases":["GHSA-xqqp-wpjp-4w5q"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Remote Service software","requires_auth":"low_privilege","summary":"A remote authenticated attacker can cause a denial of service condition in Cybozu Remote Service via unspecified vectors.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"remote_service_manager","vendor":"cybozu"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"Cybozu Remote Service 3.1.8 to 3.1.9 allows a remote authenticated attacker to cause a denial of service (DoS) condition 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":"Denial of service in Cybozu Remote Service","id":"CVE-2021-20804","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in Cybozu Remote Service","id":"CVE-2021-20805"},"packages":[],"prev":{"headline":"Missing authorization in Cybozu Remote Service","id":"CVE-2021-20803"},"products":["Cybozu Remote Service"],"published":"2021-10-13","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in Cybozu Remote Service","id":"CVE-2021-20795","kev_date_added":null,"published":"2021-10-13"},{"cvss_score":8.8,"headline":"File upload in Cybozu Remote Service","id":"CVE-2018-16169","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":8.8,"headline":"Path traversal in Cybozu Remote Service","id":"CVE-2018-16171","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":8.1,"headline":"Path traversal in Cybozu Remote Service","id":"CVE-2018-16170","kev_date_added":null,"published":"2019-01-09"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2014-7266","kev_date_added":null,"published":"2015-02-01"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2014-1983","kev_date_added":null,"published":"2014-04-19"},{"cvss_score":6.8,"headline":"Auth bypass in n/a","id":"CVE-2014-1984","kev_date_added":null,"published":"2014-04-19"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Cybozu, Inc."]},"summary":"A remote authenticated attacker can cause a denial of service condition in Cybozu Remote Service via unspecified vectors.","url":"https://insights.sbomify.com/CVE-2021-20804/"}
