Descriptions
GNU wget before 1.18 allows remote servers to write to arbitrary files by redirecting a request from HTTP to a crafted FTP resource.
GNU wget en versiones anteriores a 1.18 permite a servidores remotos escribir archivos arbitrarios redirigiendo una petición desde HTTP a una fuente FTP manipulada.
It was found that wget used a file name provided by the server for the downloaded file when following a HTTP redirect to a FTP server resource. This could cause wget to create a file with a different name than expected, possibly allowing the server to execute arbitrary code on the client.
The wget packages provide the GNU Wget file retrieval utility for HTTP, HTTPS, and FTP protocols. Security Fix: It was found that wget used a file name provided by the server for the downloaded file when following an HTTP redirect to a FTP server resource. This could cause wget to create a file with a different name than expected, possibly allowing the server to execute arbitrary code on the client.
