CVE-2021-25094

Tatsu < 3.3.12 - Unauthenticated RCE

Published Apr 25, 2022 CVSS 3.1 · 8.1 High EPSS 83.2% KEV · Not listed
Description
The Tatsu WordPress plugin before 3.3.12 add_custom_font action can be used without prior authentication to upload a rogue zip file which is uncompressed under the WordPress's upload directory. By adding a PHP shell with a filename starting with a dot ".", this can bypass extension control implemented in the plugin. Moreover, there is a race condition in the zip extraction process which makes the shell file live long enough on the filesystem to be callable by an attacker.
