Cybozu Remote Service, published on 13 Oct 2021. 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-2021-20802 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-2021-20802/ (Markdown: https://insights.sbomify.com/CVE-2021-20802/index.md)","id":"CVE-2021-20802","markdown":"https://insights.sbomify.com/CVE-2021-20802/index.md","name":"CVE-2021-20802","record":{"aliases":["GHSA-f589-pm5w-6v39"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Remote service software","requires_auth":"none","summary":"A remote attacker can inject HTTP headers to alter stored information in Cybozu Remote Service.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"remote_service_manager","vendor":"cybozu"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"HTTP header injection vulnerability in Cybozu Remote Service 3.1.8 to 3.1.9 allows a remote attacker to alter the information stored in the product.","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":"Other in Cybozu Remote Service","id":"CVE-2021-20802","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in Cybozu Remote Service","id":"CVE-2021-20803"},"packages":[],"prev":{"headline":"XML external entity in Cybozu Remote Service","id":"CVE-2021-20801"},"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":"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 remote attacker can inject HTTP headers to alter stored information in Cybozu Remote Service.","url":"https://insights.sbomify.com/CVE-2021-20802/"}
