Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20841 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ec-cube/ec-cube (Packagist): affected from 2.11.2; fixed in 2.17.2\n- ec-cube/ec-cube (Packagist): affected from 2.11.2; fixed in 2.17.2\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-2021-20841/ (Markdown: https://insights.sbomify.com/CVE-2021-20841/index.md)","id":"CVE-2021-20841","markdown":"https://insights.sbomify.com/CVE-2021-20841/index.md","name":"CVE-2021-20841","record":{"aliases":["GHSA-jc55-crg7-pr35"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"EC-CUBE e-commerce platform","requires_auth":"low_privilege","summary":"Remote authenticated attackers can bypass access restrictions in the EC-CUBE management screen to alter system settings.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"ec-cube","vendor":"ec-cube"}],"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:H/A:N","version":"3.1"},"cwes":[],"description":"Improper access control in Management screen of EC-CUBE 2 series 2.11.2 to 2.17.1 allows a remote authenticated attacker to bypass access restriction and to alter System settings via unspecified vectors.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"EC-CUBE Improper access control in Management screen","id":"CVE-2021-20841","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"EC-CUBE Cross-site request forgery (CSRF) vulnerability","id":"CVE-2021-20842"},"packages":[{"ecosystem":"Packagist","fixed":["2.17.2"],"introduced":["2.11.2"],"last_affected":[],"package":"ec-cube/ec-cube","purl":null,"source":"GHSA-jc55-crg7-pr35"},{"ecosystem":"Packagist","fixed":["2.17.2"],"introduced":["2.11.2"],"last_affected":[],"package":"ec-cube/ec-cube","purl":"pkg:composer/ec-cube/ec-cube","source":"GHSA-jc55-crg7-pr35"}],"prev":{"headline":"Cross-site scripting in Booking Package - Appointment Booking Calendar System","id":"CVE-2021-20840"},"products":["EC-CUBE 2 series"],"published":"2021-11-24","related":[{"cvss_score":8.1,"headline":"EC-CUBE Directory traversal vulnerability","id":"CVE-2020-5590","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":7.5,"headline":"Missing authorization in EC-CUBE","id":"CVE-2021-20778","kev_date_added":null,"published":"2021-07-01"},{"cvss_score":7.5,"headline":"EC-CUBE Improper input validation vulnerability","id":"CVE-2020-5680","kev_date_added":null,"published":"2020-12-03"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2008-4991","kev_date_added":null,"published":"2008-11-06"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2008-4534","kev_date_added":null,"published":"2008-10-10"},{"cvss_score":7.2,"headline":"Code injection in EC-CUBE 3 series","id":"CVE-2023-46845","kev_date_added":null,"published":"2023-11-07"},{"cvss_score":6.9,"headline":"Auth bypass in EC-CUBE 4.1 series","id":"CVE-2026-30777","kev_date_added":null,"published":"2026-03-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":["EC-CUBE CO.,LTD."]},"summary":"Remote authenticated attackers can bypass access restrictions in the EC-CUBE management screen to alter system settings.","url":"https://insights.sbomify.com/CVE-2021-20841/"}
