Arbitrary file download via client-controlled path parameter

Published Feb 4, 2022 · Updated Aug 4, 2024

Arbitrary file download in TaoCMS 3.0.1 allows remote authenticated users with administrator access to read server files. The File Management download action returns the file named by a client-controlled path parameter rather than restricting selection to managed files. Administrator access to the background interface is required; exploitation discloses files readable by the web application.
