Cybozu Remote Service, published on 13 Oct 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20795 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-2021-20795/ (Markdown: https://insights.sbomify.com/CVE-2021-20795/index.md)","id":"CVE-2021-20795","markdown":"https://insights.sbomify.com/CVE-2021-20795/index.md","name":"CVE-2021-20795","record":{"aliases":["GHSA-3r57-cvmr-xwg9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cybozu Remote Service","requires_auth":"none","summary":"A CSRF vulnerability in Cybozu Remote Service allows attackers to hijack administrator sessions and perform unauthorized actions.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"remote_service_manager","vendor":"cybozu"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-site request forgery (CSRF) vulnerability in the management screen of Cybozu Remote Service 3.1.8 to 3.1.9 allows a remote attacker to hijack the authentication of administrators and unintended operations may be performed 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":"Cross-site request forgery in Cybozu Remote Service","id":"CVE-2021-20795","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Path traversal in Cybozu Remote Service","id":"CVE-2021-20796"},"packages":[],"prev":{"headline":"Other in The installers of multiple Sony products","id":"CVE-2021-20793"},"products":["Cybozu Remote Service"],"published":"2021-10-13","related":[{"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":"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":"2024-08-03","vendors":["Cybozu, Inc."]},"summary":"A CSRF vulnerability in Cybozu Remote Service allows attackers to hijack administrator sessions and perform unauthorized actions.","url":"https://insights.sbomify.com/CVE-2021-20795/"}
