sqlmap支持自动伪静态批量检测

0x00 前言


由于还没有找到一款比较适合批量检测sql注入点的工具(proxy+sqlmapapi的方式批量检测之类的批量sql注入点检测),我的目光就转向了sqlmap。虽然sqlmap没有支持伪静态注入点的测试(需要手动添加注入标记),由于是python写的,可以快速方便的进行二次开发。

 

0x01 思路


我的思路是在有.html之类的后缀或者既没有.html或者包含”?”的url进行修改。

伪静态注入点一般都在数字,所以我就在数字后面添加注入标记。字符串的伪静态就不搞了,搞了工作量就会添加很多。

用如下的URL进行测试

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

结果如下

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

代码如下:

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

  • https://github.com/sqlmapproject/sqlmap/blob/master/lib/core/target.py

流程

<p>Sqlmap.py 116行start()->controller.py 256行setupTargetEnv()->target.py 72行_setRequestParams()->target.py 117行

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

这里检测是否使用了注入标记。

sqlmap获取完所有你指定的信息后,开始正式检测是否有注入之前,会检测是否使用了注入标记”*“,如果有的话就先处理这个注入标记的点进行测试。

这样就明白注入标记的流程,只要_setRequestParams函数调用之前处理好URL,就可以支持自动的伪静态注入的测试了。

只要在260行处添加

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)

这样就可以了。

sqlmap支持自动伪静态批量检测

这里只是单个的,要支持批量检测注入点。修改这里是不行的。

583行处

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))

一行一行读取文件里面的url。只要匹配到有问号”?”或者有注入标记”*”才进行测试。

在583处添加

    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("/")         returnList = []         for i in urlList:             i = re.sub('/.html|/.htm','', i)             if i.isdigit():                 returnList.append(i + "*")                 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):                     digitList = re.findall('/d+',i)                     for digit in digitList:                         i = i.replace(digit, digit + "*")                     returnList.append(i)                 else:                     returnList.append(i)             line = '/'.join(returnList)
