CVE-2025-30202
Data exposure via ZeroMQ on multi-node vLLM deployment
Em resumo
vLLM versões 0.5.2 a 0.8.4 expõem dados internos e arriscam lentidão em implantações multi-nó porque abrem uma porta de comunicação ZeroMQ desprotegida e acessível a qualquer pessoa na rede. Um atacante pode se conectar a essa porta para interceptar mensagens internas do sistema ou causar propositalmente problemas de desempenho.
Detalhe técnico
A implantação multi-nó do vLLM usa um socket XPUB ZeroMQ desprotegido, vinculado a todas as interfaces de rede, permitindo que clientes remotos não autenticados se conectem e recebam informações de estado interno transmitidas ou realizem ataques de esgotamento de recursos mantendo múltiplas conexões. A exploração requer acesso de rede à porta ZeroMQ do host primário e afeta implantações com paralelismo de tensor entre nós.
Resumo gerado e traduzido por IA a partir da descrição 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.
