Descriptions

The Free Booking Plugin for Hotels, Restaurant and Car Rental WordPress plugin before 1.1.16 suffers from insufficient input validation which leads to arbitrary file upload and subsequently to remote code execution. An AJAX action accessible to unauthenticated users is affected by this issue. An allowlist of valid file extensions is defined but is not used during the validation steps.

El plugin Free Booking Plugin for Hotels, Restaurant and Car Rental de WordPress versiones anteriores a 1.1.16, sufre de una insuficiente comprobación de entrada que conlleva a una carga de archivos arbitrarios y posteriormente a una ejecución de código remota. Una acción AJAX accesible a usuarios no autenticados está afectada por este problema. Es definida una lista de extensiones de archivo válidas, pero no es usada durante los pasos de comprobación

The Free Booking Plugin for Hotels, Restaurant and Car Rental is vulnerable to arbitrary file uploads due to missing file type validation via the ~/easync.php file in versions up to, and including, 1.1.15. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.
