{"id":"BIT-mediawiki-2020-27621","details":"The FileImporter extension in MediaWiki through 1.35.0 was not properly attributing various user actions to a specific user's IP address. Instead, for various actions, it would report the IP address of an internal Wikimedia Foundation server by omitting X-Forwarded-For data. This resulted in an inability to properly audit and attribute various user actions performed via the FileImporter extension.","aliases":["CVE-2020-27621"],"modified":"2025-04-03T14:40:37.652Z","published":"2024-03-06T11:13:47.809Z","database_specific":{"cpes":["cpe:2.3:a:mediawiki:mediawiki:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://gerrit.wikimedia.org/r/q/I24a240253c7a5c66dd493a68e8c23d95a17e1b21"},{"type":"WEB","url":"https://phabricator.wikimedia.org/T265810"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-27621"}],"affected":[{"package":{"name":"mediawiki","ecosystem":"Bitnami","purl":"pkg:bitnami/mediawiki"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.35.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mediawiki/BIT-mediawiki-2020-27621.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}],"schema_version":"1.7.3"}
