CVSS v3.1

9.8

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions FineCms version 5.2.0

Description The issue allows remote attackers to upload arbitrary .php files. This is possible due to a default SYS KEY value in the v5/config/system.php file, which does not require key regeneration for each installation. Attackers can exploit this via a member API swfupload action to index.php.

Recommendations For FineCms version 5.2.0, consider regenerating the SYS KEY value for each installation to prevent the use of a default key, and restrict access to the swfupload action in index.php to minimize the risk of exploitation.
