This is due to insufficient file type validation in check_mimetype(), which writes attacker-supplied remote file content to the public uploads directory before any MIME or extension check, combined with a missing capability check on new player creation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. This requires successfully exploiting a race condition, and is only exploitable if the '[fvplayer_editor]' shortcode is present, or the \"Enable profile videos\" setting is enabled."}],"title":"FV Player 8 <= 8.1.7 - Authenticated (Subscriber+) Arbitrary File Upload via videos[].fv_wp_flowplayer_field_src Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5c75cb7b-1ebe-411c-8664-848d741e40d4?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L105"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L148"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/checker.php#L181"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L46"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L1102"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db.php#L1173"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/models/db-video.php#L855"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/controller/editor.php#L36"},{"url":"https://plugins.trac.wordpress.org/browser/fv-player/trunk/controller/frontend.php#L1211"},{"url":"https://github.com/foliovision/fv-wordpress-flowplayer/releases/tag/8.1.8"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-434 Unrestricted Upload of File with Dangerous Type","cweId":"CWE-434","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"Supakiad S.
