Descriptions
A vulnerability in the filesystem permissions of Cisco NX-OS Software could allow an authenticated, local attacker to gain read and write access to a critical configuration file. The vulnerability is due to a failure to impose strict filesystem permissions on the targeted device. An attacker could exploit this vulnerability by accessing and modifying restricted files. A successful exploit could allow an attacker to use the content of this configuration file to bypass authentication and log in as any user of the device. MDS 9000 Series Multilayer Switches are affected in versions prior to 6.2(25), 8.1(1b), and 8.3(1). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I4(9) and 7.0(3)I7(4). Nexus 3500 Platform Switches are affected in versions prior to 6.0(2)A8(10) and 7.0(3)I7(4). Nexus 3600 Platform Switches are affected in versions prior to 7.0(3)F3(5). Nexus 2000, 5500, 5600, and 6000 Series Switches are affected in versions prior to 7.1(5)N1(1b) and 7.3(3)N1(1). Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22), 7.3(3)D1(1), and 8.2(3). Nexus 9000 Series Switches-Standalone are affected in versions prior to 7.0(3)I4(9) and 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 los permisos de "filesystem" del software NX-OS de Cisco podría permitir a un atacante local autenticado obtener acceso de lectura y escritura a un archivo de configuración crítico. La vulnerabilidad se debe a un fallo para imponer permisos de "filesystem" estrictos en el dispositivo objetivo. Un atacante podría explotar esta vulnerabilidad modificando y accediendo a los archivos restringidos. Su explotación con éxito podría permitir a un atacante utilizar el contenido de este archivo de configuración para omitir una autenticación e iniciar sesión como cualquier usuario del dispositivo.
