bigtreecmsbigtree

Description#

BigTree 4.3 allows full path disclosure via authenticated admin/news/ input that triggers a syntax error. NOTE: This has been disputed with the following reasoning: "The issue reported requires full developer level access to the content management system where cross site scripting is not an issue -- you already have full control of the CMS including running arbitrary PHP.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact none, availability impact none. Attack vector: network.

Weaknesses#
