Descriptions

A vulnerability in the CLI of Cisco NX-OS Software could allow an authenticated, local attacker to escalate lower-level privileges to the administrator level. The vulnerability is due to insufficient authorization enforcement. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. A successful exploit could allow an attacker to make configuration changes to the system as administrator. Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4). Nexus 3500 Platform Switches are affected in versions prior to 7.0(3)I7(4). Nexus 3600 Platform Switches are affected in versions prior to 7.0(3)F3(5). Nexus 9000 Series Switches-Standalone are affected in versions prior to 7.0(3)I7(4). Nexus 9500 R-Series Line Cards and Fabric Modules are affected in versions prior to 7.0(3)F3(5).

Una vulnerabilidad en la interfaz de línea de comandos del software NX-OS podría permitir que un atacante local autenticado escale privilegios de bajo nivel al del administrador. Esta vulnerabilidad se debe al cumplimiento insuficiente de una autorización. Un atacante podría explotar esta vulnerabilidad autenticándose en el dispositivo objetivo y ejecutando comandos que podrían conducir al escalado de privilegios. Su explotación con éxito podría permitir que el atacante realice cambios en el sistema como el administrador. Los switches de Nexus 3000 Series se ven afectados en versiones anteriores a la 7.0(3)I7(4). Los switches de Nexus 3500 Platform se ven afectados en versiones anteriores a la 7.0(3)I7(4). Los switches de Nexus 3600 Platform se ven afectados en versiones anteriores a la 7.0(3)F3(5). Los switches de Nexus 9000 Series-Standalone se ven afectados en versiones anteriores a la 7.0(3)I7(4). Los switches de 9500 R-Series Line Cards y Fabric Modules se ven afectados en versiones anteriores a la 7.0(3)F3(5).
