Quick assessment

Affected
openremote core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

OpenRemote 在 1.31.0 版本之前存在一个授权绕过漏洞。该漏洞允许某个领域（realm）的管理员冒充其他领域的网关，因为 GatewayService 仅校验网关 ID，而未校验所属领域。拥有 WRITE:ADMIN 权限的攻击者可以在一个领域内创建一个以另一领域网关 ID 命名的服务用户，从而覆盖其下游资产，并向该网关的本地网络建立 SSH 隧道。

Vulnerability Title
OpenRemote before 1.31.0 Cross-Realm Gateway Impersonation via Websocket
Source: CVE Program / CVE List V5
Vulnerability Description
OpenRemote before 1.31.0 contains an authorization bypass vulnerability that allows realm admins to impersonate gateways in other realms because GatewayService only checks the gateway ID, not the realm. Attackers with WRITE:ADMIN in one realm can create a service user named after another realm's gateway ID to overwrite its descendant assets and open SSH tunnels into its local network.
