VAR-200911-0244
Vulnerability from variot - Updated: 2023-12-18 12:11Home FTP Server 1.10.1.139 allows remote attackers to cause a denial of service (daemon outage) via multiple invalid SITE INDEX commands. Home Ftp Server is an easy to use FTP server. After the user logs in to the Home FTP Server, performing the following steps will cause the server to stop responding: 1.sock.connect((hostname, 21))2.sock.send(\"user %s\" %username)3.sock.send (\"pass %s\" %passwd)4.for i in range(1,20): sock.send(\"SITE INDEX \"+ \"a\"30i +\"\")5.sock.close(). Home FTP Server is prone to a remote denial-of-service vulnerability because it fails to handle user-supplied input. Successfully exploiting this issue allows remote attackers to crash the affected application, denying service to legitimate users. ----------------------------------------------------------------------
