### 简要描述：
系统后台权限逻辑校验存在问题，导致后台某模块功能被绕过和非授权访问
### 详细说明：
后台管理员权限校验在文件\public\class_connector.php:
```
function admin_purview() {
if ($this->fun->accept('archive', 'R') == 'filemanage' && $this->fun->accept('action', 'R') == 'batupfilesave') {
$ecisp_admininfo = $this->fun->accept('ecisp_admininfo', 'G');
$esp_powerlist = $this->fun->accept('esp_powerlist', 'G');
$gettype = false;
} else {
$ecisp_admininfo = $this->fun->accept('ecisp_admininfo', 'C');
$esp_powerlist = $this->fun->accept('esp_powerlist', 'C');
$gettype = true;
}
$arr_purview = explode('|', $this->fun->eccode($ecisp_admininfo, 'DECODE', db_pscode));
$this->esp_powerlist = explode('|', $this->fun->eccode($esp_powerlist, 'DECODE', db_pscode));
list($this->esp_adminuserid, $this->esp_username, $this->esp_password, $this->esp_useragent, $this->esp_powerid, $this->esp_inputclassid, $this->esp_softurl) = $arr_purview;
if ($gettype) {
if (empty($this->esp_username) || empty($this->esp_adminuserid) || md5(admin_AGENT) != $this->esp_useragent || md5(admin_ClassURL) != $this->esp_softurl) {
$condition = 0;
} else {
$condition = 1;
}
} else {
if (empty($this->esp_username) || empty($this->esp_adminuserid) || md5(admin_ClassURL) != $this->esp_softurl) {
$condition = 0;
} else {
$condition = 1;
}
}
if ($condition == 0) {
if ($this->fun->accept('archive', 'R') != 'adminuser' && $this->fun->accept('action', 'R') != 'login') {
header('location: index.php?archive=adminuser&action=login');
exit();
}
} else {
if ($condition == 1 && $this->fun->accept('point', 'R') == '' && $this->fun->accept('archive', 'R') == '' && $this->fun->accept('action', 'R') == '') {
header('location: index.php?archive=management&action=tab&loadfun=mangercenter&out=tabcenter');
exit();
}
}
```
逻辑校验存在问题:
if ($condition == 0) {
if ($this->fun->accept('archive', 'R') != 'adminuser' && $this->fun->accept('action', 'R') != 'login') {
header('location: index.php?archive=adminuser&action=login');
exit();
}
当archive=adminuser,但是action变量不等于login时就不会被跳转到登录页。但是在文件adminsoft\control\adminuser.php中
```
function onlogin() {
parent::start_template();
if ($this->fun->accept('logoutid', 'C') == 1) {
$this->ectemplates->assign('systemTitle', $this->lng['adminuser_login_lout_error']);
$this->fun->setcookie('logoutid', 0);
} else {
$this->ectemplates->assign('systemTitle', $this->lng['adminuser_login_login_error']);
}
$this->ectemplates->display('login');
}
function onlogin_into() {
include_once admin_ROOT . '/public/class_seccode.php';
list($new_seccode, $expiration) = explode("\t", $this->fun->eccode($_COOKIE['ecisp_seccode'], 'DECODE'));
$code = new seccode();
$code->seccodeconvert($new_seccode);
parent::start_template();
$db_table = db_prefix . "admin_member";
$linkURL = $_SERVER['HTTP_REFERER'];
```
还可以调用该类的其他方法，如方法onlogin_into()
### 漏洞证明：
http://127.0.0.1/adminsoft/index.php?archive=adminuser&action=login_into
也就是可以调用adminuser.php这个后台文件的其他功能。
