BUGTRAQ ID: 28766
Coppermine是用PHP编写的多用途集成web图形库脚本。
Coppermine的upload.php文件处理用户请求数据时存在输入验证漏洞，远程攻击者可能利用此漏洞执行SQL注入攻击。
在执行URI/URL上传时Coppermine的upload.php文件没有正确地过滤远程HTTP服务器的MIME媒体类型输入，这允许远程攻击者通过操控SQL查询请求执行SQL注入攻击。
Coppermine Photo Gallery 1.4.16
临时解决方法：
* 在upload.php文件中找到以下行：
} else {
// We will try to get the extension from the database.
$MIME_result = cpg_db_query("SELECT extension FROM {$CONFIG['TABLE_FILETYPES']} WHERE mime='$URI_MIME_type'");
// Check to see if any results were returned.
if (!mysql_num_rows($MIME_result)) {
// No results, so free up the resources.
mysql_free_result($MIME_result);
// We cannot determine an extension from the MIME type provided, so note an error. Reject the file as unsafe.
$URI_failure_array[] = array( 'failure_ordinal'=>$failure_ordinal, 'URI_name'=> $_POST['URI_array'][$counter], 'error_code'=>$lang_upload_php['MIME_type_unknown']);
// There is no need for further tests or action, so skip the remainder of the iteration.
continue;
} else {
// The was a result. Fetch it.
$extension_data = mysql_fetch_array($MIME_result);
// Release the resources.
mysql_free_result($MIME_result);
// Store the extension in $extension.
$extension = $extension_data['extension'];
}
}
并替换为：
} else {
$extension = '';
foreach ($FILE_TYPES as $ext => $typedata){
if ($typedata['mime'] == $URI_MIME_type){
// Store the extension in $extension.
$extension = $ext;
break;
}
}
if (!$extension){
// We cannot determine an extension from the MIME type provided, so note an error. Reject the file as unsafe.
$URI_failure_array[] = array( 'failure_ordinal'=>$failure_ordinal, 'URI_name'=> $_POST['URI_array'][$counter], 'error_code'=>$lang_upload_php['MIME_type_unknown']);
// There is no need for further tests or action, so skip the remainder of the iteration.
continue;
}
}
