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-2021-45471 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mediawiki (Bitnami): affected all versions; fixed in 1.37.1\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-2021-45471/ (Markdown: https://insights.sbomify.com/CVE-2021-45471/index.md)","id":"CVE-2021-45471","markdown":"https://insights.sbomify.com/CVE-2021-45471/index.md","name":"CVE-2021-45471","record":{"aliases":["BIT-mediawiki-2021-45471","GHSA-mrv7-g7p3-qw62","UBUNTU-CVE-2021-45471"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki","requires_auth":"none","summary":"Blocked IP addresses can bypass restrictions to edit EntitySchema items in MediaWiki, allowing unauthorized data modification.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"mediawiki","vendor":"mediawiki"}],"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":[],"description":"In MediaWiki through 1.37, blocked IP addresses are allowed to edit EntitySchema items.","ecosystems":["Bitnami"],"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":"Missing authorization in n/a","id":"CVE-2021-45471","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"fedoraproject:fedora","products":["fedoraproject:fedora","mediawiki:mediawiki"],"type":"missing_authorization","year":"2021"},"n_packages":1,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-45472"},"packages":[{"ecosystem":"Bitnami","fixed":["1.37.1"],"introduced":["0"],"last_affected":[],"package":"mediawiki","purl":"pkg:bitnami/mediawiki","source":"BIT-mediawiki-2021-45471"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-45470"},"products":["n/a"],"published":"2021-12-24","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-08-04","vendors":["n/a"]},"summary":"Blocked IP addresses can bypass restrictions to edit EntitySchema items in MediaWiki, allowing unauthorized data modification.","url":"https://insights.sbomify.com/CVE-2021-45471/"}
