CVE-2025-30202
Data exposure via ZeroMQ on multi-node vLLM deployment
En resumen
vLLM versiones 0.5.2 a 0.8.4 exponen datos internos y arriesgan ralentización en implementaciones multi-nodo porque abren un puerto de comunicación ZeroMQ desprotegido accesible a cualquiera en la red. Un atacante puede conectarse a este puerto para interceptar mensajes internos del sistema o causar deliberadamente problemas de rendimiento.
Detalle técnico
La implementación multi-nodo de vLLM utiliza un socket XPUB ZeroMQ desprotegido vinculado a todas las interfaces de red, permitiendo que clientes remotos no autenticados se conecten y reciban información de estado interno transmitida o realicen ataques de agotamiento de recursos manteniendo múltiples conexiones. La explotación requiere acceso de red al puerto ZeroMQ del host primario y afecta implementaciones que utilizan paralelismo de tensor entre nodos.
Resumen generado y traducido por IA a partir de la descripción oficial.
vLLM is a high-throughput and memory-efficient inference and serving engine for LLMs. Versions starting from 0.5.2 and prior to 0.8.5 are vulnerable to denial of service and data exposure via ZeroMQ on multi-node vLLM deployment. In a multi-node vLLM deployment, vLLM uses ZeroMQ for some multi-node communication purposes. The primary vLLM host opens an XPUB ZeroMQ socket and binds it to ALL interfaces. While the socket is always opened for a multi-node deployment, it is only used when doing tensor parallelism across multiple hosts. Any client with network access to this host can connect to this XPUB socket unless its port is blocked by a firewall. Once connected, these arbitrary clients will receive all of the same data broadcasted to all of the secondary vLLM hosts. This data is internal vLLM state information that is not useful to an attacker. By potentially connecting to this socket many times and not reading data published to them, an attacker can also cause a denial of service by slowing down or potentially blocking the publisher. This issue has been patched in version 0.8.5.
