Joomla Extension - OrdaSoft.com - Authenticated, Privileged Remote Code Execution in OrdaSoft Joomla Gallery extension for Joomla < 6.2.7 - The extensions saveWatermark() copied an uploaded file into a web-accessible directory using the client-supplied filename exactly as sent, with no extension check, no content check, and no filename sanitisation of any kind. An authenticated core.manage user could upload a .php file disguised with an image Content-Type header and execute it directly by requesting the resulting path.
