### 简要描述：
任意文件下载
### 详细说明：
```
用友icc客户系统存在任意文件下载漏洞，漏洞文件common/getfile.jsp源码如下：
<%@ page contentType="text/html;charset=UTF-8" %>
<%@ page import="java.io.*,com.ufida.icc.util.*,java.util.*" %><%
String fullPath = "";
String f="";
f = request.getParameter("p");
if(CommonUtil.validateParam(f)){
f = "";
}
f = CommonUtil.filtParam(f);
if(f == null || f.equals("")){
out.print("请传入文件名。
");
return;
}
f = f.substring(f.lastIndexOf("/")+1);
String extName = f.substring(f.lastIndexOf(".")+1);
if(extName.equals(f)){
out.print("请传入正确的文件名,带后缀
");
return;
}
String basePath = null;
String baseUrl = null;
baseUrl = SystemProperties.instance().webBaseUrl;
basePath = SystemProperties.instance().webUploadPath;
fullPath = basePath + f;
fullPath = fullPath.replace("\\","/");
String fullPathFileName = fullPath.substring(fullPath.lastIndexOf("/")+1);
String fullPathFile = fullPath.replace(fullPathFileName,"");
File fileLoad = new File(fullPathFile, fullPathFileName);
if(fileLoad.exists()){
OutputStream outp = null;
FileInputStream in = null;
String typeName = "application/octet-stream";
try{
outp= response.getOutputStream();
byte b[] = new byte[1024];
response.setHeader("Content-disposition", "attachment;filename=" + fullPathFileName);
response.setContentType(typeName);
long fileLength = fileLoad.length();
String length = String.valueOf(fileLength);
response.setHeader("Content-Length", length);
in = new FileInputStream(fileLoad);
int n = 0;
while ((n = in.read(b)) != -1) {
outp.write(b, 0, n);
}
outp.flush();
}catch(Exception e){
out.println("下载失败：" + e.getMessage());
}finally{
if(in != null){
in.close();
in = null;
}
if(outp != null){
outp.close();
outp = null;
out.clear();
out = pageContext.pushBody();
}
}
}else{
out.print("文件"+fullPathFileName+"不存在。
");
}
%>
