{"id":"CVE-2021-32630","details":"Admidio is a free, open source user management system for websites of organizations and groups. In Admidio before version 4.0.4, there is an authenticated RCE via .phar file upload. A php web shell can be uploaded via the Documents & Files upload feature. Someone with upload permissions could rename the php shell with a .phar extension, visit the file, triggering the payload for a reverse/bind shell. This can be mitigated by excluding a .phar file extension to be uploaded (like you did with .php .phtml .php5 etc). The vulnerability is patched in version 4.0.4.","aliases":["GHSA-xpqj-67r8-25j2"],"modified":"2026-08-07T17:28:06.450843Z","published":"2021-05-20T17:15:07.773Z","references":[{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/issues/994"},{"type":"ADVISORY","url":"https://github.com/Admidio/admidio/releases/tag/v4.0.4"},{"type":"EVIDENCE","url":"https://github.com/Admidio/admidio/security/advisories/GHSA-xpqj-67r8-25j2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/admidio/admidio","events":[{"introduced":"0"},{"fixed":"d850a871e349091e0f038f0b6d60a71f53403162"}],"database_specific":{"cpe":"cpe:2.3:a:admidio:admidio:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"4.0.4"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v4.0.3","v4.0.2","v4.0.1.1","v4.0.1","v4.0.0","v4.0-Beta.5","v4.0-Beta.4","v4.0-Beta.3","v4.0-Beta.2","v4.0-Beta.1","v3.2-Beta.1","v3.1.5","v3.0.6","3.0-Beta.3","3.0-Beta.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-32630.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
