由于還沒有找到一款比較適合批量檢測sql注入點的工具(proxy+sqlmapapi的方式批量檢測之類的批量sql注入點檢測),我的目光就轉向了sqlmap。雖然sqlmap沒有支持偽靜態注入點的測試(需要手動添加注入標記),由于是python寫的,可以快速方便的進行二次開發。
我的思路是在有.html之類的后綴或者既沒有.html或者包含"?"的url進行修改。
偽靜態注入點一般都在數字,所以我就在數字后面添加注入標記。字符串的偽靜態就不搞了,搞了工作量就會添加很多。
用如下的URL進行測試
#!bash
http://www.site.com/index.php/index/id/14
http://www.site.com/index.php/newsContent/id/341.html
http://www.site.com/show/?29-575.html
結果如下
#!bash
http://www.site.com/index.php/index/id/14*
http://www.site.com/index.php/newsContent/id/341*.html
http://www.site.com/show/?29*-575*.html
代碼如下:
#!python
if re.search('html|htm|sthml',url) or url.find("?") == -1:
flag = 0
suffix = ""
if re.search('html|htm|sthml',url):
suffix = "." + re.search('html|htm|sthml',url).group()
urlList = url.split("/")
returnList = []
for i in urlList:
i = re.sub('\.html|\.htm','', i)
if i.isdigit():
returnList.append(i + "*")
flag = 1
else:
returnList.append(i)
url = '/'.join(returnList) + suffix
returnList = []
if flag == 0:
for i in urlList:
if re.search('html|htm|sthml',i):
digitList = re.findall('\d+',i)
for digit in digitList:
i = i.replace(digit, digit + "*")
returnList.append(i)
else:
returnList.append(i)
url = '/'.join(returnList)
print url

流程
Sqlmap.py 116行start()->controller.py 256行setupTargetEnv()->target.py 72行_setRequestParams()->target.py 117行
#!python
if kb.processUserMarks is None and CUSTOM_INJECTION_MARK_CHAR in conf.data:
message = "custom injection marking character ('%s') found in option " % CUSTOM_INJECTION_MARK_CHAR
message += "'--data'. Do you want to process it? [Y/n/q] "
test = readInput(message, default="Y")
if test and test[0] in ("q", "Q"):
raise SqlmapUserQuitException
else:
kb.processUserMarks = not test or test[0] not in ("n", "N")
if kb.processUserMarks:
kb.testOnlyCustom = True
這里檢測是否使用了注入標記。
sqlmap獲取完所有你指定的信息后,開始正式檢測是否有注入之前,會檢測是否使用了注入標記"*
",如果有的話就先處理這個注入標記的點進行測試。
這樣就明白注入標記的流程,只要_setRequestParams函數調用之前處理好URL,就可以支持自動的偽靜態注入的測試了。
只要在260行處添加
#!python
if re.search('html|htm|sthml',conf.url) or conf.url.find("?") == -1:
flag = 0
suffix = ""
if re.search('html|htm|sthml',conf.url):
suffix = "." + re.search('html|htm|sthml',conf.url).group()
urlList = conf.url.split("/")
returnList = []
for i in urlList:
i = re.sub('\.html|\.htm','', i)
if i.isdigit():
returnList.append(i + "*")
flag = 1
else:
returnList.append(i)
conf.url = '/'.join(returnList) + suffix
returnList = []
if flag == 0:
for i in urlList:
if re.search('html|htm|sthml',i):
digitList = re.findall('\d+',i)
for digit in digitList:
i = i.replace(digit, digit + "*")
returnList.append(i)
else:
returnList.append(i)
conf.url = '/'.join(returnList)
logger.info(conf.url)
這樣就可以了。
效果圖
這里只是單個的,要支持批量檢測注入點。修改這里是不行的。

#!python
for line in getFileItems(conf.bulkFile):
if re.match(r"[^ ]+\?(.+)", line, re.I) or CUSTOM_INJECTION_MARK_CHAR in line:
found = True
kb.targets.add((line.strip(), conf.method, conf.data, conf.cookie, None))
一行一行讀取文件里面的url。只要匹配到有問號"?"或者有注入標記"*"才進行測試。
在583處添加
#!python
if re.search('html|htm|sthml',line) or line.find("?") == -1:
flag = 0
suffix = ""
if re.search('html|htm|sthml',line):
suffix = "." + re.search('html|htm|sthml',line).group()
urlList = line.split("/")

for i in urlList:
i = re.sub('\.html|\.htm','', i)
if i.isdigit():

flag = 1
else:
returnList.append(i)
line = '/'.join(returnList) + suffix
returnList = []
if flag == 0:
for i in urlList:
if re.search('html|htm|sthml',i):
