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

#!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

结果如下

#!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

代码如下：

#!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

#!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

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

#!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)

这样就可以了。效果图

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。

0x03 sqlmap支持批量自动检测伪静态

#!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

#!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("/") 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)
