本文主要是介绍通达OA header身份认证绕过漏洞复现，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
通达OA是中国通达公司的一套协同办公自动化软件，通达OA2013，通达OA2016，通达OA2017 存在身份认证绕过漏洞，攻击者可以利用漏洞生成cookie，实现未授权访问。
1.漏洞级别
高危
2.漏洞搜索
fofa title="office Anywhere"
如需指定版本可以搜title="office Anywhere 2013"
3.漏洞复现
3.1 获取有效cookie

- 注：手动测试时，需要注意Content-Type为必须项，否则生成的cookie无效。（我在这里被坑了好久 导致一直没成功复现）
返回的Set-Cookie即为我们需要的有效cookie。
3.2 实现登录
将上一步获取的cookie设置到header中。
- 注： 这个参数名需要修改成Cookie 而不是Set-Cookie
直接请求后台
url/general/
即可复现成功，网页端可以将cookie手动添加进去然后访问
至此漏洞就复现完成了。
