禅道项目管理系统身份认证绕过漏洞

禅道项目管理系统身份认证绕过漏洞​

禅道项目管理系统存在身份认证绕过漏洞,远程攻击者利用该漏洞可以绕过身份认证,调用任意API接口并修改管理员用户的密码,并以管理员用户登录该系统,配合其他漏洞进一步利用后就可以实现完全接管服务器。

影响版本​

16.x <= 禅道项目管理系统< 18.12（开源版）
6.x <= 禅道项目管理系统< 8.12（企业版）
3.x <= 禅道项目管理系统< 4.12（旗舰版）

    - 禅道系统某些API设计为通过特定的鉴权函数进行验证，但在实际实现中，这个鉴权函数在鉴权失败后并不中断请求，而是仅返回一个错误标志，这个返回值在后续没有被适当处理。此外，该系统在处理某些API时未能有效检查用户身份，允许未认证的用户执行某些操作，从而绕过鉴权机制。
