Descriptions

The mailSend function in the isMail transport in PHPMailer before 5.2.18 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted Sender property.

La función mailSend en el transporte isMail en PHPMailer en versiones anteriores a 5.2.18 podrían permitir a atacantes remotos pasar parámetros extra al comando mail y consecuentemente ejecutar código arbitrario a través de una \" (barra invertida comillas dobles) en una propiedad Sender manipulada.

PHPMailer version 5.2.17 suffers from a remote code execution vulnerability.
