OpenRemote Cross-Realm Gateway Impersonation Vulnerability

Source agreement

Tam uyum

Evidence confidence

Short explanation

An authorization vulnerability in OpenRemote allows realm administrators to impersonate gateways in other realms because GatewayService only validates the gateway ID without checking the realm (S0).

Why does it matter?

Attackers with WRITE:ADMIN privileges in one realm can create service users named after another realm's gateway ID, overwriting descendant assets and establishing SSH tunnels into the local network (S0).

What should be done?

  • Follow the vendor advisory (S0)

WRITE:ADMIN yetkisine sahip saldırganlar başka bir realm'in ağ geçidi kimliğini taklit ederek varlıkların üzerine yazabilir ve yerel ağa SSH tünelleri açabilir (S0).

Show the technical text from the sources

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.
