Descriptions

osTicket 1.10.1 provides a functionality to upload 'html' files with associated formats. However, it does not properly validate the uploaded file's contents and thus accepts any type of file, such as with a tickets.php request that is modified with a .html extension changed to a .exe extension. An attacker can leverage this vulnerability to upload arbitrary files on the web application having malicious content.

osTicket 1.10.1 proporciona una funcionalidad para subir archivos html con formatos asociados. Sin embargo, no valida correctamente los contenidos de los archivos subidos y por lo tanto acepta cualquier tipo de archivo, como en el caso de una peticiÃ³n tickets.php que se modifica con una extensiÃ³n .html cambiada a una extensiÃ³n .exe. Un atacante podrÃa utilizar esta vulnerabilidad para subir archivos arbitrarios que contengan contenidos maliciosos a la aplicaciÃ³n web.

osTicket version 1.10.1 suffers from a remote shell upload vulnerability.
