Horde/Form/Type.php contains a vulnerable class that handles image upload in forms. When the Horde_Form_Type_image method onSubmit() is called on uploads, it invokes the functions getImage() and _getUpload(), which uses unsanitized user input as a path to save the image. The unsanitized POST parameter object[photo][img][file] is saved in the $upload[img][file] PHP variable, allowing an attacker to manipulate the $tmp_file passed to move_uploaded_file() to save the uploaded file. By setting the parameter to (for example) ../usr/share/horde/static/bd.php, one can write a PHP backdoor inside the web root. The static/ destination folder is a good candidate to drop the backdoor because it is always writable in Horde installations. (The unsanitized POST parameter went probably unnoticed because it's never submitted by the forms, which default to securely using a random path.)"}, {"lang": "es", "value": "Fue encontrada una ejecuci\u00f3n remota de c\u00f3digo en Horde Groupware Webmail versi\u00f3n 5.2.22 y versi\u00f3n 5.2.17. El archivo Horde/Form/Type.php contiene una clase vulnerable que maneja la carga de im\u00e1genes en formularios. Cuando se llama al m\u00e9todo Horde_Form_Type_image en la funci\u00f3n onSubmit () en las cargas, hace un llamado a las funciones getImage() y _getUpload(), que utiliza una entrada de usuario no autorizada como un path para guardar la imagen. La falta de saneamiento del par\u00e1metro POST object[photo][img][file] se guarda en la variable PHP $upload[img][file], lo que permite a un atacante manipular el archivo $tmp_file pasado a move_uploaded_file() para guardar el archivo cargado. Al establecer el par\u00e1metro en (por ejemplo) ../usr/share/horde/static/bd.php, se puede escribir un backdoor PHP dentro de la web root. La carpeta de destino static/ es un buen candidato para abandonar la backdoor y siempre se puede escribir en las instalaciones Horde.
