Vulnerability Title
Coder vulnerable to unauthenticated SSRF via Azure Instance Identity Endpoint
Vulnerability Description
Coder allows organizations to provision remote development environments via Terraform. Versions prior tp 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 are vulnerable to unauthenticated semi-blind Server-Side Request Forgery (SSRF) via the Azure instance identity endpoint (`POST /api/v2/workspaceagents/azure-instance-identity`). An external attacker can force the Coder server to issue HTTP GET requests to arbitrary internal or external hosts by submitting a crafted PKCS#7 signature. The server does not return the target's response body, but error messages in the API response reveal whether the target is reachable and what type of failure occurred. Versions 2.24.5, 2.29.13, 2.30.8, 2.31.12, 2.32.2, and 2.33.3 patch the issue. As a workaround, if the Azure identity-auth mechanism is not being used then restrict access to the corresponding endpoint (`/api/v2/workspaceagents/azure-instance-identity`) using ingress firewall and/or proxy ACLs.

Vulnerability Title
Coder 服务端请求伪造漏洞
Vulnerability Description
Coder是Coder组织开源的一个可以在公共或私有云基础设施中设置开发环境的应用程序。 Coder存在服务端请求伪造漏洞,该漏洞源于Azure实例身份端点存在未经身份验证的半盲服务端请求伪造问题,攻击者可通过提交特制PKCS#7签名强制服务器向任意内部或外部主机发出HTTP GET请求,服务器不返回目标响应体,但错误消息可揭示目标是否可达及失败类型。
