Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-21366 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-21366/ (Markdown: https://insights.sbomify.com/CVE-2020-21366/index.md)","id":"CVE-2020-21366","markdown":"https://insights.sbomify.com/CVE-2020-21366/index.md","name":"CVE-2020-21366","record":{"aliases":["GHSA-jhmp-h4x3-p89g"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"GreenCMS","requires_auth":"low_privilege","summary":"An attacker can exploit a Cross-Site Request Forgery flaw in GreenCMS to add new users and gain unauthorized privileges.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"greencms","vendor":"njtech"}],"cvss":{"score":8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 vulnerability in GreenCMS v.2.3 allows an attacker to gain privileges via the adduser function of index.php.","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 n/a","id":"CVE-2020-21366","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2020-21377"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-21365"},"products":["n/a"],"published":"2023-06-20","related":[{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-11670","kev_date_added":null,"published":"2018-06-01"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-11671","kev_date_added":null,"published":"2018-06-01"},{"cvss_score":8.1,"headline":"Path traversal in n/a","id":"CVE-2022-28918","kev_date_added":null,"published":"2022-04-26"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2018-12604","kev_date_added":null,"published":"2018-06-20"},{"cvss_score":7.1,"headline":"Green CMS 2.x SQL Injection via cat Parameter","id":"CVE-2019-25573","kev_date_added":null,"published":"2026-03-21"},{"cvss_score":7.1,"headline":"Green CMS 2.x Path Traversal Arbitrary File Download","id":"CVE-2019-25574","kev_date_added":null,"published":"2026-03-21"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-12-10","vendors":["n/a"]},"summary":"An attacker can exploit a Cross-Site Request Forgery flaw in GreenCMS to add new users and gain unauthorized privileges.","url":"https://insights.sbomify.com/CVE-2020-21366/"}
