Title
Docker Model Runner OCI Registry Client Vulnerable to Server-Side Request Forgery (SSRF)
Summary
Docker Model Runner (DMR) is software used to manage, run, and deploy AI models using Docker. Prior to version 1.1.25, Docker Model Runner contains an SSRF vulnerability in its OCI registry token exchange flow. When pulling a model, Model Runner follows the realm URL from the registry's WWW-Authenticate header without validating the scheme, hostname, or IP range. A malicious OCI registry can set the realm to an internal URL (e.g., http://127.0.0.1:3000/), causing Model Runner running on the host to make arbitrary GET requests to internal services and reflect the full response body back to the caller. Additionally, the token exchange mechanism can relay data from internal services back to the attacker-controlled registry via the Authorization: Bearer header. This issue has been patched in version 1.1.25. For Docker Desktop users, enabling Enhanced Container Isolation (ECI) blocks container access to Model Runner, preventing exploitation. However, if the Docker Model Runner is exposed to localhost over TCP in specific configurations, the vulnerability is still exploitable.

Antes de la versi\u00f3n 1.1.25, Docker Model Runner contiene una vulnerabilidad SSRF en su flujo de intercambio de tokens del registro OCI. Al extraer un modelo, Model Runner sigue la URL del realm del encabezado WWW-Authenticate del registro sin validar el esquema, el nombre de host o el rango de IP. Un registro OCI malicioso puede establecer el realm a una URL interna (por ejemplo, http://127.0.0.1:3000/), haciendo que Model Runner, ejecut\u00e1ndose en el host, realice solicitudes GET arbitrarias a servicios internos y refleje el cuerpo completo de la respuesta de vuelta al llamador. Adem\u00e1s, el mecanismo de intercambio de tokens puede retransmitir datos de servicios internos de vuelta al registro controlado por el atacante a trav\u00e9s del encabezado Authorization: Bearer. Este problema ha sido parcheado en la versi\u00f3n 1.1.25. Para los usuarios de Docker Desktop, habilitar el Aislamiento Mejorado de Contenedores (ECI) bloquea el acceso del contenedor a Model Runner, previniendo la explotaci\u00f3n. Sin embargo, si Docker Model Runner est\u00e1 expuesto a localhost sobre TCP en configuraciones espec\u00edficas, la vulnerabilidad sigue siendo explotable."

              "value": "Docker Model Runner (DMR) is software used to manage, run, and deploy AI models using Docker. Prior to version 1.1.25, Docker Model Runner contains an SSRF vulnerability in its OCI registry token exchange flow. When pulling a model, Model Runner follows the realm URL from the registry\u0027s WWW-Authenticate header without validating the scheme, hostname, or IP range. A malicious OCI registry can set the realm to an internal URL (e.g., http://127.0.0.1:3000/), causing Model Runner running on the host to make arbitrary GET requests to internal services and reflect the full response body back to the caller. Additionally, the token exchange mechanism can relay data from internal services back to the attacker-controlled registry via the Authorization: Bearer header. This issue has been patched in version 1.1.25. For Docker Desktop users, enabling Enhanced Container Isolation (ECI) blocks container access to Model Runner, preventing exploitation. However, if the Docker Model Runner is exposed to localhost over TCP in specific configurations, the vulnerability is still exploitable."
