CVE-2020-13424Network attack vector

Authenticated file disclosure via undisclosed mechanism

Published May 23, 2020 · Updated Aug 4, 2024

Authenticated local file disclosure in XCloner for Joomla before 3.5.4 allows remote authenticated users to read server files. XCloner states that exploit details were not published, so the vulnerable request handler and its incorrect file-path operation remain undisclosed. Access requires an authenticated Joomla session, and exploitation exposes files readable by the server-side component without reported write or service-interruption impact.
