Descriptions

ftpd in OpenBSD 4.3, FreeBSD 7.0, NetBSD 4.0, Solaris, and possibly other operating systems interprets long commands from an FTP client as multiple commands, which allows remote attackers to conduct cross-site request forgery (CSRF) attacks and execute arbitrary FTP commands via a long ftp:// URI that leverages an existing session from the FTP client implementation in a web browser.

ftpd en OpenBSD 4.3, FreeBSD 7.0, y NetBSD 4.0 interpreta como múltiples comandos los comandos largos desde un cliente FTP, lo que permite a atacantes remotos llevar a cabo ataques de falsificación de petición en sitios cruzados (CSFR) y ejecutar comandos FTP de su elección a través de una URI ftp:// larga que aprovecha una sesión FTP existente en la implementación de un cliente FTP en un navegador web.
