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-2013-4303 in the wild and no public exploit code.\n\nAffected product: Mediawiki Mediawiki. 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-2013-4303/ (Markdown: https://insights.sbomify.com/CVE-2013-4303/index.md)","id":"CVE-2013-4303","markdown":"https://insights.sbomify.com/CVE-2013-4303/index.md","name":"CVE-2013-4303","record":{"aliases":["DEBIAN-CVE-2013-4303","GHSA-rxq7-cw42-v5ch"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki","requires_auth":"none","summary":"Remote attackers can execute arbitrary scripts via cross-site scripting in the MediaWiki API due to improper extension detection.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"mediawiki","vendor":"mediawiki"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"includes/libs/IEUrlExtension.php in the MediaWiki API in MediaWiki 1.19.x before 1.19.8, 1.20.x before 1.20.7, and 1.21.x before 1.21.2 does not properly detect extensions when there are an even number of \".\" (period) characters in a string, which allows remote attackers to conduct cross-site scripting (XSS) attacks via the siprop parameter in a query action to wiki/api.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":true,"headline":"Cross-site scripting in MediaWiki","id":"CVE-2013-4303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mediawiki:mediawiki","products":["mediawiki:mediawiki"],"type":"xss","year":"2013"},"n_packages":0,"n_references":5,"next":{"headline":"Auth bypass in n/a","id":"CVE-2013-4304"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2013-4302"},"products":["MediaWiki"],"published":"2019-12-11","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2023-37303","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-29904","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-29906","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2022-28205","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28206","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28209","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2021-36126","kev_date_added":null,"published":"2021-07-02"}],"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":"2024-08-06","vendors":["Wikimedia Foundation"]},"summary":"Remote attackers can execute arbitrary scripts via cross-site scripting in the MediaWiki API due to improper extension detection.","url":"https://insights.sbomify.com/CVE-2013-4303/"}
