Descriptions

Avaya Fabric Connect Virtual Services Platform (VSP) Operating System Software (VOSS) before 4.2.3.0 and 5.x before 5.0.1.0 does not properly handle VLAN and I-SIS indexes, which allows remote attackers to obtain unauthorized access via crafted Ethernet frames.

Avaya Fabric Connect Virtual Services Platform (VSP) Operating System Software (VOSS) en versiones anteriores a 4.2.3.0 y 5.x en versiones anteriores a 5.0.1.0 no maneja adecuadamente los índices VLAN e I-SIS, lo que permite a atacantes remotos obtener acceso no autorizado a través de marcos Ethernet manipulados.

Avaya Fabric Connect VSP, under specific conditions, can accept and process specially crafted and spoofed Ethernet frames, which can lead to unauthorized access to devices intended to be secured from untrusted traffic sources. The vulnerability is caused by mishandling VLAN and I-SID indexes within the Fabric infrastructure. Version 4.1.0.0 is affected.
