CVE-2021-25094 DETAIL

Modified

--------------------------------------------------------------------------------

This vulnerability has been modified since it was last analyzed by the NVD. It
is awaiting reanalysis which may result in further changes to the information
provided.


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.
