CVE-2025-64513

Estado: AplazadaCrítica (9.3)—

Milvus is an open-source vector database built for generative AI applications. An unauthenticated attacker can exploit a vulnerability in versions prior to 2.4.24, 2.5.21, and 2.6.5 to bypass all authentication mechanisms in the Milvus Proxy component, gaining full administrative access to the Milvus cluster. This grants the attacker the ability to read, modify, or delete data, and to perform privileged administrative operations such as database or collection management. This issue has been fixed in Milvus 2.4.24, 2.5.21, and 2.6.5.

If immediate upgrade is not possible, a temporary mitigation can be applied by removing the sourceID header from all incoming requests at the gateway, API gateway, or load balancer level before they reach the Milvus Proxy. This prevents attackers from exploiting the authentication bypass behavior.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Un atacante no autenticado puede explotar una vulnerabilidad en versiones anteriores a la 2.4.24, 2.5.21 y 2.6.5 para omitir todos los mecanismos de autenticación en el componente Milvus Proxy, obteniendo acceso administrativo completo al clúster de Milvus. Esto otorga al atacante la capacidad de leer, modificar o eliminar datos, y de realizar operaciones administrativas privilegiadas como la gestión de bases de datos o colecciones. Este problema ha sido solucionado en Milvus 2.4.24, 2.5.21 y 2.6.5. Si una actualización inmediata no es posible, se puede aplicar una mitigación temporal eliminando el encabezado sourceID de todas las solicitudes entrantes a nivel de gateway, API gateway o balanceador de carga antes de que lleguen al Milvus Proxy. Esto evita que los atacantes exploten el comportamiento de omisión de autenticación."
