CVSS 8.8 · High EPSS 0,64%

Kerentanan Unrestricted Upload of File with Dangerous Type. Skor CVSS 3.1 8.8 (High) menurut wordfence.com.

Deskripsi (NVD)

The FV Player 8 plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 8.1.7 via the check_mimetype function. 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.
