Script execution via administrator tracking-code fields
Published Oct 23, 2023 · Updated Aug 2, 2024
Stored cross-site scripting in Concrete CMS 9.2.1 allows remote authenticated users to run JavaScript through header or footer tracking-code fields. Those fields intentionally render administrator-supplied JavaScript on every page rather than neutralizing it, so the vendor disputes that this behavior is a security flaw. Exploitation requires administrator dashboard permission and a user to load a page; the HttpOnly Concrete CMS session cookie remains unreadable to the script.
