### 简要描述：
ThinkSNS某功能平行权限
### 详细说明：
问题发生在微吧模块
代码apps\weiba\index.action.php
public function postEdit() 这个方法有判断权限
不过到了代码
行561这里并没有判断被编辑的帖子是否是当前用户发的！
```
public function doPostEdit(){
$weiba = D('weiba_post')->where('post_id='.intval($_POST['post_id']))->field('weiba_id,attach')->find();
if ( !CheckWeibaPermission( '' , $weiba['weiba_id'] ,'weiba_edit') ){
if ( !CheckPermission('weiba_normal','weiba_edit') ){
$this->error('对不起，您没有权限进行该操作！',true);
}
}
$checkContent = str_replace(' ', '', $_POST['content']);
$checkContent = str_replace('<br />', '', $checkContent);
$checkContent = str_replace('<p>', '', $checkContent);
$checkContent = str_replace('</p>', '', $checkContent);
$checkContents = preg_replace('/<img(.*?)src=/i','img',$checkContent);
$checkContents = preg_replace('/<embed(.*?)src=/i','img',$checkContents);
if(strlen(t($_POST['title']))==0) $this->error('帖子标题不能为空',true);
if(strlen(t($checkContents))==0) $this->error('帖子内容不能为空',true);
preg_match_all('/./us', t($_POST['title']), $match);
if(count($match[0])>30){ //汉字和字母都为一个字
$this->error('帖子标题不能超过30个字',true);
}
$post_id = intval($_POST['post_id']);
$data['title'] = t($_POST['title']);
$data['content'] = h($_POST['content']);
$data['attach'] = '';
if ( $_POST['attach_ids'] ){
$attach = explode('|', $_POST['attach_ids']);
foreach ( $attach as $k=>$a){
if ( !$a ){
unset($attach[$k]);
}
}
$attach = array_map( 'intval' , $attach);
$data['attach'] = serialize($attach);
}
$res = D('weiba_post')->where('post_id='.$post_id)->save($data);
if($res!==false){
$post_detail = D('weiba_post')->where('post_id='.$post_id)->find();
if(intval($_POST['log'])==1){
D('log')->writeLog($post_detail['weiba_id'],$this->mid,'编辑了帖子“<a href="'.U('weiba/Index/postDetail',array('post_id'=>$post_id)).'" target="_blank">'.$post_detail['title'].'</a>”','posts');
}
//同步到微博
$feedInfo = D('feed_data')->where('feed_id='.$post_detail['feed_id'])->find();
$datas = unserialize($feedInfo['feed_data']);
$datas['content'] = '【'.$data['title'].'】'.getShort(t($checkContent),100).' ';
$datas['body'] = $datas['content'];
$data1['feed_data'] = serialize($datas);
$data1['feed_content'] = $datas['content'];
$feed_id = D('feed_data')->where('feed_id='.$post_detail['feed_id'])->save($data1);
model('Cache')->rm('fd_'.$post_detail['feed_id']);
return $this->ajaxReturn($post_id, '编辑成功', 1);
}else{
$this->error('编辑失败',true);
}
}
```
### 漏洞证明：
第一步 用普通帐号
发布一个帖子
然后编辑
访问
/index.php?app=weiba&mod=Index&act=postEdit&post_id=1
