One such internal service exposes server configuration and credential material without authentication, relying only on the request originating locally. Because the forged requests originate from the server process, that check is satisfied. An unauthenticated attacker can therefore retrieve stored credentials and use them to obtain an administrative session, resulting in full compromise of the server and all of its services. Altium 365 cloud deployments are not affected, as the affected endpoint is disabled in cloud mode.

| Description | A server-side request forgery (SSRF) vulnerability exists in the UnifiedLogin service of Altium Enterprise Server. An unauthenticated network attacker can cause the server to issue outbound HTTP requests to a destination of the attacker's choosing, including internal services that are reachable only from the server itself. One such internal service exposes server configuration and credential material without authentication, relying only on the request originating locally. Because the forged requests originate from the server process, that check is satisfied. An unauthenticated attacker can therefore retrieve stored credentials and use them to obtain an administrative session, resulting in full compromise of the server and all of its services. Altium 365 cloud deployments are not affected, as the affected endpoint is disabled in cloud mode. | |
