由于还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。
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

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
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。修改这里不是不行的。

https://github.com/sqlmapproject/sqlmap/blob/master/lib/core/option.py583行处
#!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)
