Vulnerability from fkie_nvd - Published: 2025-11-10 22:15 - Updated: 2025-11-12 16:19
Severity ?
9.3 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
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.

      "value": "Milvus es una base de datos vectorial de c\u00f3digo abierto creada para aplicaciones de IA generativa. 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 autenticaci\u00f3n en el componente Milvus Proxy, obteniendo acceso administrativo completo al cl\u00faster de Milvus. Esto otorga al atacante la capacidad de leer, modificar o eliminar datos, y de realizar operaciones administrativas privilegiadas como la gesti\u00f3n 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 actualizaci\u00f3n inmediata no es posible, se puede aplicar una mitigaci\u00f3n 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 omisi\u00f3n de autenticaci\u00f3n."
