OrdaSoft Touch Slider (mod_os_touchslider) below 5.4.6 - Unauthenticated Slider Image Deletion and Content Replacement

OrdaSoft Touch Slider (OS Touch Slider / OrdaSoft Joomla Slider) versions 1.0.0 to 5.4.5 route every data-management operation through modOsTouchSliderHelper::getAjax(), reached via Joomla core com_ajax, with no user check, no authorise() call and no CSRF token. An unauthenticated attacker can delete any slider image by its sequential ID with a plain GET request, and can upload a zip that replaces the slider tables (#__os_touch_slider and #__os_touch_slider_text) site-wide with attacker-supplied content. No login is required. Update to 5.4.6 or later. Until then, unpublish or uninstall the module.
